Well I went to see Saw 3 on opening night last night, and I have to say that I liked it just as much as the other two movies of the series.
It was gory, well thought out, and had that certain twist at the end that Jigsaw always pulls out. Even some of the traps were pretty original compared to the earlier movies.
I highly recommend that people go and see this movie, it was worth the $7.00 for a ticket in a crowded theater.
