Sadly I've yet to see the original but it is one I really want to see. I see it is directed by William Lustig and loved maniac cop, really want to see the second and then you have the one and only Tom Savini.
The remake was interesting. I did like the POV shots. I get people get sick of found footage kind of stuff but this was different as it is like we are seeing through the eyes of a killer. You can kind of at times feel bad for what he has seen e.g. as a child but then also repulsed at what he does.
I kind of feel that without this it might have been just another slasher type film, but this adds something fresh to it. I saw someone online said something interesting about it, the fact normally when a victim is going places your thinking don't go in there etc. With this your thinking no don't kill her, it kind of adds an interesting twist.
I see a lot of people weren't keen on Elijah Wood's performance but I really enjoyed it. I liked the fact he wasn't the typical scary looking person, adding a lot of realism. Sometimes serial killers can look normal or even good looking e.g. Bundy. It reminds me of the end of a great film 8mm, which has Nicholas Cage as a private investigator trying to find out if a film a widow has found in her dead husband's safe is fake or an actual real snuff film. Near the end one of the antagonists mask comes off to reveal a normal looking person who still lives with his mother and he says "what did you expect, a monster." Great moment. Also I found sometimes the way he looked, staring into the mirror and so on had a creepy feel to it.
I thought the effects were also great. Only criticism was that he was able to never be seen. I mean he chases someone through a station which is empty but you'd think there would be cameras. However really enjoyed the film.
