I've also been a fan of Chucky and the Child's Play series from a very early age. The first two films of the series in particular I took a liking to early on. I even had a full-size Chucky doll I used to play with when I was five years old. I'd do the whole "Dumballa...give me the power I beg of youuu!" thing and would totally freak out my Aunt with it. There's a picture of me hugging it somewhere...I'll have to see if I can drag that up for nostalgia's sake. As for my favorite of the films now, I'd have to say the original...but I like them all (except for Seed of Chucky, ick).
I have not seen Curse of Chucky yet, but as I've said on the forums before, I am really looking forward to seeing it when I decide to pick up the DVD. I like hearing all the decent reviews that its been getting on the site.
