After watching Saw 1, I was pleasantly suprised and was desperate to watch Saw 2, then go through all of them in order. That plan did fall through, but I did stay up all night and watch Saw 2 - possibly one of the few films that can join the 'Sequels Better Than The Original' Club. It was a lot better! There was more gore, rather than pathetically hiding it, it had 2 big plot twists near the end and Jigsaw's looming menace worked a treat, even though he was in front of 20 cops!
The traps in the film, including a furnace, a blade box, a door and various others, were rather clever and seemed realistic while still quite violent. Throw in the air of mistrust, a search for a link between all of the 'subjects' and some Saw 1 references, and you have a general sum up of the film.
SPOILER ALERT - TO AVOID A SPOILER, SKIP THE NEXT 2 PARAGRAPHS. THANK YOU...
The one thing the film lacked was a near end scene like in Saw 1, with a big chase, and all out battle to the death amongst various characters. Instead, you get one of the characters going insane and trying to kill everyone to find a number on their neck that would become part of a combination to open a safe. Although quite tense it did seem rather funny in a "WHY THE HELL ARE YOU DOING THAT?!?" sense when he can't trust anyone and cuts the number of his own neck to see it, before dying of blood loss!
Another moment of stupidity is where one of the characters is trying to find an antidote for a poison in a box. She puts one hand in to grab the antidote, drops it, tries to remove her hand to find that it is trapped by 4 blades. She then thinks it's a great idea to puts the other hand in to get the spilt antidote and fails, ending up getting stuck!
Backing away from spoilers now, the film is all-round very tense, especially near the end, and in a way, by having a similar ending but with some very unfamiliar twists, the film became much more creepy and intense than the first.
Just to sum up how good I thought the film was, I WILL be watching the rest of the Saw Septology!
