I have a weird history with this franchise. The first one I saw was Child's Play 2 at like age 9 and for some reason, it got to me more than a movie has. Maybe it was because I was dealing with a death in the family but I dunno, Chucky freaked the crap outta me- the robotic type non-fluid movements, the piercing blue eyes and evil grin, the red hair with overalls and colorful clothes. The name Chucky itself is brilliant for this character as it is playful but still sounds harsh phonetically.
Since then, I've had a weird fascination with the franchise despite not wanting to watch them and knowing they are just B-movie horror films. Still, I'm interested to see where it goes but yea, I think the older ones scared me because of how Chucky moved due to practical effects. CGI Chucky that didn't use voodoo isn't nearly as affective at surface level. Technology gone wrong blah! The voodoo element added to the already sinister idea the franchise originally invented.
