-- Event Horizon
Seriously?
If anything, I think Event Horizon is UNDERrated. I know a lot of people hate it just because it's a Paul W.S. Anderson flick. It's actually his only film I find quite enjoyable, but I'm a sucker for movies where Sam Neill goes insane and starts killing people.
My list would include:
Star Trek II: The Wrath of Khan
Star Wars: Episode V - The Empire Strikes Back
Jurassic Park III
I enjoy Event Horizon, I just don't think outside being a fairly decent horror flick that it's as good and some people hype it up to be. Visually it looks great, and I like the cinematography-- for the most part-- but there's nothing-- to me-- that stands out about the script or the movie in general.
