I've just seen the film, and I'm sorry, but it is simply too awful for anything but straight to dvd. Sean's character is a cookie cutter villain. He stumbles through the lame dialog, sounding as if he phoned in his lines. There is no insight into his character and Sean is never left to just simply run with it in hopes of turning Uncle Frank into something other than a worm under a rock. At least in Cash he brought to life a very complex and entertaining villain. In this case, he more or less just sits and chews on the scenery. There are no surprises in the plot as every move is telegraphed by the characters well in advance of the actions that are supposed to thrill you. Purefoy does a slightly better job of actually emoting anything other than the lowlife character that you're supposed to believe he is. This whole film just skipped over the whole concept of character development, trying instead for jolting plot twists and turns that simply didn't surprise in the least.
All that being said, I'm not cancelling my pre-order of the dvd because I want it for my collection.
