Bride of Chucky was the true turning point for the franchise, and though they hadn't 100% embraced comedy at this point like they did in the followup, there's still at least as much humour and reference in this one as there is elements of "horror". The central premise of a horror road trip, where the lead couple each believe the other party is the culprit (and are both wrong) is pretty solid, as is the final showdown, but the connective tissue is a bit wishy washy, and the inability to commit to a tone doesn't serve the movie very well, putting it at a lower point than any of its predecessors.
Final rating:★★½ - Had a lot that appealed to me, didn’t quite work as a whole.
