How would you evaluate his horror filmography?
The Evil Dead is a very good movie though ultimately it's nothing more that a low budget splatterfest in the woods.
Evil Dead II is fun. Splatter and slapstick in the woods. Superior production values here though sometimes I find myself preferring the straight horror of the first.
Army of Darkness. I barely consider this a horror movie. It's more of a slapstick action-adventure. It's not one I rewatch often, which I guess means I'm not that big a fan of it, even if I quite enjoy it when I inevitably do sit down and watch it.
Drag Me to Hell is a very good movie. A proper looney tunes horror. Raimi repeats his slapstick style here. I enjoy Alison Lohman as the lead and think the story here is great.
I haven't seen The Gift.
