Omg most of my favourites fall into this category!
Cocktail
Passenger 57 (particularly awful is liz hurleys "acting" seconded by a truly DREADFUL cheesy cliché ridden script!)
Under siege
Long kiss goodnight
The Rock
Roadhouse
Commando (notable for a very young Alyssa Milano too)
The glimmer man
Face/off
Con air
Next 2007 (also Nicholas cage - he picks some seriously dodgy scripts!)
Burlesque
Last action hero
Last Boy Scout
Broken arrow
Adventures in babysitting
Monster in law
Basically you'll likely not go wrong with any of the cheesy action stars - Schwarzenegger, Bruce Willis, Steven Seagal, Nick cage at a push
"Critters is hilariously bad but I love it!" I don't know ANYBODY else who's seen these - basically more adult piss take of gremlins - which I also love!
"I can’t think of the name of it (it has Alan Rickman in it) and they are actors in a Star Trek type programme who get mistaken for real space explorers by aliens who get them to help them from being attacked by other aliens. It’s better than it sounds!" - galaxy quest! Yes it's a cracker
"I’m going old school: Police Academy, Caddyshack, National Lampoons, Uncle Buck, Planes, Trains and Automobiles, Brewsters Millions." Totally excellent suggestions. Can I add bill & Ted movies to this (anyone else so excited they're doing a new one?!)
I've recently "discovered" a "new" one (new to me at least)
Morning glory - Harrison ford as a curmudgeonly, offensive formerly highly respected hardcore journalist stuck presenting a "fluffy" morning "news" show with Diane Keaton with Rachel macadams as a naive, optimistic, hard done by producer - it's utter nonsense but fun!
And to anyone who's seen it I need only say "frittata"
