Okay, so I rewatched it, and you could definitely tell there were similarities to Exit Wounds and Today You Die. However, feeling like a combination of the two, I feel like it missed out on the strong points of both. It felt like Seagal's main mission (avenging his wife) was just sort of a side show. The whole plot with the stolen gold had rather little payoff (pun intended), and ultimately I think the movie would have been better had they taken the Today We Die route where Seagal is a criminal trying to go clean, and in the process leads the prisoners to retake the prison from the hostage takers. That being said, the action sequences were good, and Seagal gets a good amount of screen time. It was really just sort of plot and plot details that made it fall flat for me.
Edit: Also the production values were pretty decent.
