I've not seen any of the films but I watch as much as I can about them if that makes sense? (Currently housebound so not getting to see latest films) and I'm aware I'm writing this 2 hours into the ceremony but I haven't seen any results yet. Don't have sky either.
So this is purely my very biased feelings on the nominations
Best film:
Roma - I hate Alfonso Cuaron for shafting Tess geritsen over gravity so I absolutely hope this film wins nothing for that reason. It's also been roundly slated on mn and elsewhere as self indulgent wankery focusing on dog shit! So...yea hopefully wins nothing
A star is born - I love gaga and Brad cooper and music based films so this is up my street but i also love la Streisand and Judy garland and those are BIG shoes to fill plus not keen on remakes
Blackkklansman - interesting premise for a film but as a white woman not sure I feel safe commenting. It does remind me of my lovely granda who always on subject of kkk declared them facist cowards hiding behind masks
Green book - I love social history and films based on true stories and I love mahershala Ali who I first saw in a small tv role and he leapt from the screen incredible charisma and force of character while not overacting or making it deliberately all about him, he was just playing a cop in lie to me and even then I was googling him and thinking he was one to watch. I know he's won an Oscar already but I adore him
Vice - meh. I'm interested in politics and social history but films abut politicians rarely work
Black panther - I'm a big fan of marvel comics and films and this stars actually another lie to me actor who again really stood out in a very small part. I then watched him in creed I'd been a huge fan of the rocky films and this really revived them I feel, then around the time I watched creed fruitvale station as it was on tv and I'd been googling Michael b Jordan and this performance had rave reviews. It's a heartbreaking story and he does indeed put in another amazing performance in it. Plus he's bloody funny on chat shows
The favourite - I love Olivia Colman but this isn't my kinda thing at all it's too obvious, too silly on the comedy side. I err more toward the sarcastic, satirical side of things than more towards almost slapstick
Bohemian rhapsody - while I was a wham!/George Michael girl I loved queen and Freddie too and for my generation he was the first big really well known celeb to die of AIDS and I remember how shocking and heartbreaking and unfair that felt. Freddie was an incredible showman. Again I've seen and loved other performances by rami too
Best actor:
Christian bale - can't stand the man, so far up his own arse he can eat his own throat!
Rami - love him, as an actor and he seems a good sort in person too
Bradley cooper - love him, very funny but seems kinda introverted too and seems like a genuine nice guy which is something underrated now
Viggo mortensen - not a fan. Don't rate him as an actor and seems up himself in real life. Think he thinks he's underrated? He's not
Willem Defoe - love him as an actor great baddie
Best actress
Olivia Colman - love her but as I said the film isn't to my taste. I'll be chuffed for her if she wins but not surprised if she doesn't
Glenn close - adore her. Fabulous actress who's out in some incredible performances but I think has been overlooked as she won't suck up to certain people
Lady gaga - love her. Mad as a box of frogs but love her and what I've seen of her acting in this I love too
Melissa McCarthy - loved her since Gilmore girls but not liked everything she's done gross out and slapstick type stuff isn't for me but this film is a whole other ball game and looks right up my street
I don't know the Roma actress and made my feelings clear on the film
Best supporting actor
Mahershala Ali - love him as I said be delighted if he wins!
Richard e grant - love him too and love what I've seen so far of the film and it would be lovely if he wins but I suspect he's pissed off the wrong people (apparently he's brutally honest what he really thinks of certain Hollywood people)
Sam Elliott - love him too, but another one who's apparently rubbed certain people up the wrong way
Sam Rockwell don't know him don't fancy the film
Adam driver - don't like him. Don't like him as an actor hate him as Kylo ren (why'd they cast someone so damn ugly as the child of Harrison ford and Carrie fisher?!) overrated imo
Best supporting actress
Regina King - bloody love her! Seen her in loads and always like her, very funny open lady on chat shows and the film really appeals to me
Amy Adams - generally I love her but I don't like the clips I've seen of her in this and don't fancy the film
Rachel weisz generally love her but don't like the look of the film
Emma stone don't know here never seen her in anything and she comes across very poorly on chat shows, no character
Roma actress no interest in
Best director
Alfonso Cuaron - will be pissed off if he wins
Spike lee - his work is very worthy but I don't find it entertaining or engaging but then it's not aimed at me
Cold War? Not even heard of this one
Yorgos - the favourite - like I say not my cuppa
Adam McKay - not fancying the film not familiar with the director
Just checked winners pleased with all except best director, strongly suspecting bribery & corruption there!
Not checked out the frocks yet either but wtf Is that abomination at 0043?! Who is that? That honestly looks like someone's granny let loose with a sewing machine and 70's curtain fabric that was rejected as too tasteless even for the 70's!! Maya Rudolph - mate with a name like that you REALLY need a better stylist
Rachel weisz dress looks like a maternity dress! Is she pregnant?
Thought gaga looks fantastic but hoped for more original from her, though i guess her dressing classically is a rebellion of sorts
LOVE Kiki lanes look - elegant, glamorous but unusual too
I like the gown-cede think it looks fab
Not loving the yellow and spike lee looks like a demented psychedelic chauffeur!
Love Marie kondos look elegant and pretty
Loved Richard e grants outfit and his dd is stunning!
Linda cardellini wtf! Columbo 70's boudoir housecoat gone very wrong!
Regina King looks effortlessly fabulous
Angela Bassett love it but I'm an 80's girl and that's 80's-tastic
Melissa McCarthy love it! Kinda thing I'd wear
Glenn close - nope! Seen her look much better
Tina fey looks gorgeous
Love Amy poehlers I wore some very similar outfits in the 80's occasionally with piano ties and musical note braces 
Amy Adams phwoar! But then I definitely would anyway she's stunning
Alison Janney love it
Olivia Colman - love the colour not sure I like the style, she's actually quite petite and that seems to overwhelm her
Charlize gorgeous as ever
Emma stone - nope!
Tessa Thompson oh no! Looks like a loo roll dolly!! She's a fabulous figure this is not flattering
Laura dern seems to be wearing a 90's bridesmaids dress
J lo - yuk!
Mahershala Ali his wife's dress? What on earth?
