The Child's Play movies are some of my favorites. Despite not taking themselves too seriously there is some good tension in those flicks. The original is a classic in my mind. The second is also pretty good. The third, when the kid goes off to military school, gets a bit weird but I'll still watch it. Bride of Chucky is watchable for the laughs alone. Seed of Chucky just blew. **** that movie.
All of the Leprechauns are cult classics for me
I recently watched them all on Netflix. Warwick Davis makes that series.
28 Days and Weeks are great movies. 28 Weeks has, probably, the most intense first-15 minutes of any horror flick I can remember seeing.
Pet Sematary 1 and 2 still freak me out to this day.
I've never seen the Hellraiser flicks so I can't speak on those..
