Just watched this on daytime TV, and while it was a reasonable way to pass a lazy 1h40mins, I certainly wouldn't want to have paid to watch it. Lots of sleazy double-dealing, treachery and betrayal and high body counts. Reasonably entertaining, but not to be taken seriously! I think the worst part for me was when the grieving widow went into a reverie and we were shown a full song-length's worth of flashbacks of their happy times together, composed from a montage of clips already seen in the film so far! There were one or two twists that kept up a little interest, although in my opinion there was maybe a twist too many right at the end, which made the whole plot more unbelievable. One character appeared to have had a complete personality transplant which didn't really ring true! Decent acting performances all-round though.
