Halloween 2 is set in a creepy hospital that only has a single patient and several staff members. Where are the other patients? Who knows. It maintains its horror vibe with a synth-track to vibe it up with. It introduces the misguided sister twist, brought about by John Carpenter.
I have to expand on Carpenter’s treatment of the film though. Carpenter has knocked the sequel and its sibling aspect, a product of necessity as he needed to write more story while also feeling there was no more story. This is a failing on his part and I think it is really wrong to leave him out of the equation for the films baggage. Did he want to only have Michael in a single movie? Sure. But he still wrote the sequel.
At its heart, Halloween II feels like a slasher and lacks some of the soul of the original. If you read my review of that, you will see I am in the minority that did not really enjoy myself. However, I can objectively see more artistry there and a more full attempt at something unique. This is not that.
Halloween 2 bring back some nudity, ups the violence, adds some wonky story elements, and has a couple of cool vibe scenes. Overall though, it takes a less interesting direction with the story. It is not all waste, but it is never great either.
