The Prophecy 3: The Ascent
This really isn't a particularly good series. Christopher Walken does not save this film like he did the previous two. The story is lacklustre and the rest of the cast are not very good. The villain gets changed out at the end of the film and it being a big plot point, it isn't particularly focused on. The main villain (by screen time, at least), Zophael played by Vincent Spano, is where the film spends most of its focus. Vincent is very boring in the role and fails to be convincingly menacing at any point. It would be hard to replace Christopher Walken at the best of times, but Vincent isn't even worth the effort. The film is, essentially, boring shit.
There are two more films in the franchise. Straight to video, filmed in the same year, no Christopher Walken... so I'm not going to bother with those. The first two Prophecy films were worth the watch but the story really did conclude in the second film as they had nothing for the third.
