Decent Film-Major holes (SPOILERS!)

Rating: Null/10 (3 November 2004)

I just watched "Saw" and although I enjoyed it, I have some major problems with it.
The first was when Dr. Gordon didn't attempt to saw through the very old and rotting sewer pipe he was chained to instead of the chain. One of the first things I would have tried.
Then at the end when he couldn't reach the phone with the box, and he started taking off his shirt I figured he was going to retrieve the phone with it as he instructed Adam to do to get the tape recorder at the beginning. Never mind the actual saw he used to chop off his foot, which would have also reached the phone.
There were also several times when the killer should have been shot...by the cops and by Adam at the end, while the wife should have shot Zep when she has the chance as well.
I also didn't like it when Glover's character chased Zep. One minute they were in the apartment and the next they were in a high speed chase in cars ????? WTF
And the last question...WHY ZEP? He actually showed some compassion for the killer in the Patch Adams moment near the beginning when he told the Dr. the patient's name was John. All of the other victims were shown to be not living their lives to their potential in some way or another, but I can't recall why Zep was chosen.
This film had a lot of potential, but it looked like they just ran out of money and said frig it. I hope they do a better job on the sequel.
