Army of Darkness is adult entertainment.
Trapped in time. Surrounded by evil. Low on gas. Good use of the word satire.
Date Movie borders the territory between hilarious and just stupid.
Attack of the Killer Tomatoes! is, in my opinion, just over the border. Bunch of kids having a fun time with a movie studio. Better than most home/vacation movies tho.
Snakes on a plane? Somewhere between 'just gave up entirely' and 'f*ck you'.
