@ Jacques; For starters, here's something for you to meddle over: how on earth did the Agent Strahm and etc. know that Amanda was aiding Jigsaw and that she was his apprentice? There you go. Honestly, there's no answer for it unless you take the "it must have happened off camera!" claim that most fan boys take (no offense). So, I've defended my "plot holes" claim. Now, onto "very unrealistic"; as an audience member, you have to have realized that if Rigg would have done ANYTHING differently in that movie, the whole trap and film would have been ruined, the whole film required a massive stretch of disbelief. How in the hell did Rigg's apartment get flipped topsy-turby, in what must have been in just hours, with not a soul noticing? Honestly, the damn chair trap would have been virtually impossible to bring into the apartment without a neighbor calling the police saying, "there's some weird shit going down next door!" Anyway, if you have answers to these (which are just for starters) little impossibility questionnaires of mine, I welcome a logical response. I'm not bagging on you, your free to enjoy "Saw IV" all you want, but I didn't dig it at all and it's flawed logic, acting, plot, etc. throughout was insulting to me as a member of the audience.
