All the deaths were told in a flashback format, which killed any suspense for the scene

That the whole sequence with everyone in the house was on tape and Donnie Wahlberg's kid was in the same room they were in

I hated Amanda being so emotional. I hated the inescapable death scenes - which seemed to just be death for the sake of death. However, when we realize that Jigsaw himself didn't agree with how Amanda was handling these situations it made more sense. I thought they had let the central idea slip away and were just going for death after death, but of course, when it was all said and done, they had it right and put the film back on track.

I'm sure I'd like it better the second time, but other than the Jeff scenes and the flashbacks to Saw I & Saw II stuff, I didn't like it as I was watching it. I thought the scenes with Jigsaw and the nurse weren't very interesting and the skull operation was excessive. Of course, again, with the finale, a lot of these scenes hold more weight than originally perceived to. I was really glad Amanda got shot, because as Donnie said it best "You're no fucking Jigsaw bitch!". They really laid some good groundwork for SAW IV with Jeff's daughter, the mysterious WAX COVERED TAPE etc...should be decent.

1) That the film picks up directly where Saw II left off.
2) Donnie Whalberg returning, despite rumors he left the project before shooting.
3) All the scenes with Angus Macfadyen.
4) The g-o-r-e.
5) The death of one of the weaker characters in the franchise (Amanda).

1) The death of Dina Meyer's character. I was hoping she'd finally have a chance to develop her character, but not here. At least she got a pretty wicked death scene.
2) The subplot between the doctor, Jigsaw, and Amanda. This is all they could come up to set-up the groundwork to let death and destruction happen? Other than the gore scenes this subplot provided, when the film focuses on this material, the film nearly comes to a complete stand still. As I mentioned earlier, at least it led to the death of the Amanda character.
3) The ending ---
3a) I did not like the numerous twists that Jigsaw was against murder (or that's what it came off to me as) and that Amanda was behind most (if not all) the murders from all the previous films. I did not like the fact that this twist pretty much fucking repeated itself with ending Jeff's character arc. Now there's lazy screenwriting and then there's some lazy fucking screenwriting (which this is).
3b) The fact that the doctor was Jeff's wife.
3c) The fact that we did not get to see the doctor's head blown off. If there was ever a kill scene that should've been shown in this movie, this should've been the film's money shot.
3d) I thought everyone was saying this was going to be the last Saw flick with the help of the creators -- then why the set-up for the sequel?
