Dina did a great job in it and seeing her act with another of my favs (Lance Henrikson) was just awsome.
For those who don't like the site of blood and skipped 'Saw' cause of it, this is another one you may want to skip.
Dennis Hopper...usually very good in this type of role was just way too over the top, probably my least fav part of the movie.
All and all I rather enjoyed it.
Very disturbing in parts.
Add to all that, Dina is the first name to go with the credits. She gave a pretty good performance.
