The DVD comes with a few extras, such as a commentary from the writers (which I would've listened to but I had no desire to see the film again) and a few deleted scenes, as well as an alternate ending that actually made me laugh. Part of me thinks that I would prefer it to what actually happened (which is presumably there to give the sequel less explaining to do).
This film comes from the writers behind Saws 4 through 7 (which is IN GLORIOUS 3D, apparently), and it shows in every trap, every bloody hook and every tripwire within that house. Do not think me squeamish; I liked the first Saw movie and thought it was genuinely well done (especially the final twist), but as I was watching this I thought it was too over the top. To the extent that the Collector of the title would need years of planning just to do half of the stuff that he does throughout the film, although as we see he doesn't get that long.
While tripwires that operate mechanisms to kill are nothing new in themselves (again, think Saw 1), this guy takes it to a whole new level. Seriously, The Collector is the Rube Goldberg of execution devices. I was half expecting the Family Guy Breakfast Machine to make an appearance at some point.
No doubt this gorefest would please Saw fanatics while they wait for the next one but anyone else (and I mean anyone - even if you liked other horror this probably won't appeal to you) would be better off staying away from the box.
