I will not spoil anything but I thought Saw X was very good. Not just as a horror movie but as a movie.
Tobin Bell just plays the character so damn good. HIs timing and pacing are excellent. There are some scenes where everybody is laughing and you can tell it was planned.
Very solid, ending was a little rough but overall I thought it was a good experience.
The only thing I will note is this is supposed to happen between saw 1 and Saw 2. Amanda has aged enough it will throw you off.
