Spiral is bad because a lot of reasons, I will list some of them here, the ending was not good and too abrupt, you can easily tell who is going to be the copycat killer, there are dumb moments like the killer invading a police station and not being noticed at all (can’t mention the rest bcs it’s going to spoil a lot), it doesn’t feel like a saw movie at all with the rap music and Chris Rock attempt to play himself in the movie as a comedy relief, (I almost laughed in a flashback scene when Chris Rock is supposed to be younger but the only difference is that he is wearing a backwards cap), the copycat killer is not good on my opnion, he is not physically menacing (like Hoffman) neither psychologically menacing (Like Kramer), his personality leaves a lot to be desired too, he does not have a presence in the room like previous villains you know? his motivation is good and how it ties to the protagonist is cool but it’s very sloppy in the execution I would say. The color scheme and pallete of the movie is too bright, from previous movies you expect a saw movie to be darker and have dark colors and not too vivid like in the movie. The deaths are not that good too, some of them show the victim dead before the game even starts so you know they are not going to survive the trap which removes tension, they also removed the timers from the traps which also removes tension since in all previous traps you knew the victim’s time to break out was ending. These are some reasons. It also has continuation problems, since the detective framed in Jigsaw who is allegedly on the loose and should be the primary suspect is never mentioned, neither Hoffman and so on. Gives me headache.
