The Saw movies are those we go into with the lowest of expectations, and even then there have been instances of utter disappointment (think Saw 3D or Jigsaw). But now, for almost the first time since Saw II in 2005, there finally is a "good" Saw movie. Yes, actually good.
Saw X does two very important things that make it work so well. The first is that we now have a movie where John Kramer is finally the main character. Rather than having to learn about him through his victims, like was so for the 8 other movies he was in, we finally get to know John Kramer through John Kramer. The second is that we're finally on John's side, essentially rooting for a serial killer, because the "players" in this movie are written to be some of the most disgustingly scummy people on Earth.
Saw X is much longer (with a runtime of 118 minutes) compared to the 9 other movies (all of which average at 90), and is paced much slower too; which quite honestly works really well. The games are decent, the violence is unwatchable (which in Saw language means it's good) and we also get a few fun Easter eggs.
There is yet one major disappointment, but that's spoiler territory since it has to do with the ending, so I will ignore that for now. Other than that, the movie was surprisingly good and I honestly did enjoy it more than I thought I would. If you have been keeping up with the Saw movies, definitely go check it out in cinemas!
