I was around 15 when the first "Childs Play" came out, first catching up with it on rental vhs. Didn't take long for this, as well as parts 2 and 3, to end up on the "index of restricted movies" though.
My fave is clearly "Bride of Chucky", the only part imho which gets the mix of scares and laughs really working....and Jennifer Tilly is pretty hot in it too.
2nd place would go to "Childs Play 2"; I really like the showdown in the toy factory.
