These are movies that I consider somewhat underrated or overlooked mainly because my friends either haven't seen/heard of them or I thought they were amazing for what they were yet other people didn't, so take from this list what you will.
Automaton Transfusion - Very low budget "zombie"-type movie
Battle Royale - Asian film, kids are taken to an island and forced to kill each other until only one remains.
Black Christmas (original) - Possibly the birth of the slasher film. Killer stalks a sorority house for reasons unknown.
The Blair Witch Project - Under appreciated now, but was ground breaking at the time. Saw it in the theater and didn't know if it was real or fake for the longest time, it was also the first movie to run a successful viral marketing campaign on the internet. (most profitable movie of all time as well)
Brick - Hard to explain this one, just a cool movie.
Cube - Great lower budget Canadian horror/sci-fi movie, reminds me a little of SAW, just a little. A bunch of people wake up in a room and have no clue how they got there... the whole movie is about them trying to get out. The sequel isn't terrible, but not as good, and the prequel is down right awful.
District B13 - Action mixed with a ton of parkour
The Fountain - I didn't really care for it the first time watching, but after watching it again I enjoyed it more.
High Tension (Haute Tension) - Original and US version are almost the same, and despite the cop out ending I thought it was underrated.
The Host - Mutated whale/fish creature terrorizes the banks of a river in the middle of a city. Another Asian flick.
Ichi The Killer - And yet another Asian flick... Dude kills people with blades on his shoes.
Oldboy - Guy gets kidnapped and then released 15+ years later and vows to find who kidnapped him and get revenge. The ending is completely ****ed up. Heard rumblings of a US remake, ugh.
The Orphanage (which someone mentioned already) - Great Spanish horror/suspense.
Pan's Labyrinth - while it had some success, I still think it's underrated
Splinter - Came out last year, probably one of the better horror movies I've seen lately.
Sunshine (as mentioned before) - I thought the whole thing was pretty good even with the weird "Event Horizon" type ending act.
The Thing - Probably one of the best horror movies ever made that still stands up to viewings today and one of my favorite movies.
