I actually liked Saw O: !!!
I guess im in the minority, most reviews i read were of people that hated the acting and gave the movie an overall thumbs down. I had not read any spoilers and decided to give it a try. I did not think the acting was extremely poor. which i was lead to believe. I am not saying that it flowed 100% either. there will be no awards in that category in my book. But I think the puppet was creepy. The death devices were all pretty crafty. I like how the killer just toyed with them leaving clues here and there. It kept things mysterious. I like the photographer character. I think he played his role well. I also like the music and all the creative artistic touches.
Spoiler:
I had the killer picked right from the beginning. But remimber thinking, that was too easy. Nevertheless, I didnt think past that and when the killer was revealed at the end it was a total suprise to me. I will definately be awaiting the sequel
