I agree, but then I'm a difficult-to-please git!
I like about one film a decade, and my list of dislikes is huge:
Feel-good movies: waste of my time - trite, unsatisyfing and they don't convince me.
Rom-coms: usually corny, cheesy, predictable, cliched and saccharine. (Esp Richard Curtis, but I make an exception for FWAAF because it was the first of its kind and I do have good memories of seeing it when it came out long ago.)
Thrillers: my favourite genre - but so hard to find good ones. I'm incredibly sqeuamish, so a lot of these are ruled out for me. Can't stand extreme violence, blood or guts. I remember The Sixth Sense - very good and I love a twist.
Epics: love an epic, but they rarely live up to the hype. I haven't seen Gladiator because of the violence, but I'm sure it's an amazing film and would love it in many other ways. Similarly, I couldn't watch Saving Private Ryan but I admire Spielberg enormously and salute him for showing what war is really like, even if I can't take it. I'm planning to see Oppenheimer, and bracing myself. Also, have never seen Schindler's List, but again I'm sure it's superb. My career involved me with work with Holocaust survivors and I find the subject almost unbearable.
Don't mind emotionally harrowing films if the message/story is worth it.
Childrens/family films: please, no more now my children are grown up (except for superb classics like The Railway Children).
I'm old, so these films which I consider fairly recent, will seem ancient to you, but these are the few films I've seen in recent decades which I think are excellent:
Howards End
The Magdalene Sisters
Empire of the Sun (I was an extra in that one!)
Master and Commander
The Godfather (but that really is old...sorry)
Three Billboards Outside Ebbing, Misouri
The Others
The Sixth Sense
The Village
