Plot-holes or misunderstanding (SPOILER)

Rating: 7/10 (18 April 2005)

First of all, I liked the movie big time, especially if I got to compare it with the last two horror/thriller movies that I saw lately which were "Exorcist  the beginning", a hell of boredom & "Ring2", not that good Anyway I have some comments here; I don't know if they are actually plot-holes or just I didn't quite understand them, here we go: 1-If Adam was hired by the cop to trace Dr. Gordon, then who was that freaky corpse that appeared to him when he opened the door back at his place when the lights went off? 2-The same thing, what was the point of that scene in the garage when the murderer crawled out of Dr. Gordon's car, was it just to Booo him & that is it? 3- If you opened ur door & find some freak behind it, or just got attacked by some masked weirdo in the garage late at night, aren't that a call for you to call the police, plus these aren't that kind of events that take you half of the movie to give the audience the "Oh, now I remember, I remember everything" line, I guess if me myself woke up to find myself locked & chained in an old bathroom , the first thing will pop up in my mind is the strangest thing happened to me , unless I am used to such freaking events! 4-If the dead body (The patient John) is the one who electrocuted Adam & Gordon (or was it Zepp) all the time, then how come they didn't see him making any slight move while his pushing the button to electrocute them, & were was this electrocuting tool all the time, since he had the gun in one hand & the cassette in the other 5-Finally I know that may sound useless but depending on the fact that Gordon didn't know that the dead body on the floor ST the murderer, why he didn't tie up his shirt in the jigsaw & throw it over the gun & drag it so he can shoot his chain instead of cutting his leg, I know his nerve was on peak, but it's cutting his leg that we are talking about here! Yet I liked the movie, regardless that "Zepp, u bastard" scene which cracked me up
