What is a movie that "looks like" it would suck, but actually is well written and acted and a good time?

Tucker and Dave vs. Evil. Looks like another dumb Netflix original, but it was one of the best horror/comedies I’ve seen.

Speaking of the genre, big nods to another one - Little Evil.

It Follows - just read the premise of the film and tell me it doesn’t sound dumb… Then go watch it

Oh and Colossal!!! Ann Hathaway stars in this bizarre and very deep movie about a giant monster that can be controlled from a playground. Amazing movie. Trust me
