For as small as he was, Chucky was evil as an all get out.
I like that in a guy.
Granted he was the imitation-vodoun-posessed by a serial killer variation of the standard "talking doll" mythology...but still. The problem with the films though is that the only "person" that Chucky could find that was as smart as him was another doll. I mean really, if he scared 'em that much why didn't the folks at least insist on a refund?
Bunch of nitwits if you ask me. I would have made a deal with Chucky, something along the lines of "Consider me your transportation. I'm just gonna take you to a place so you can kill a LOT of people. Here? There's only 4 folks and after us, what'll you have? Days, heck, even weeks before you can get anyplace else." Once he was appeased and his little doll eyes sparkled, I'd give him a list of personal enemies.
Hell, as long as I had a homicidal doll, I'd take advantage of the situation.
Once my enemies were dead? I'd zap his ass in the microwave. Can't have a talking doll that knows all my secrets hanging around now can I?
