The Worst of the Worst, Bad acting, good movie if you are under 12 years old as my nephew loves it,
The problem is that it doesn't stay true to spirit of the original Superman films (I, II, III, and IV) with all the sci-fi bs like the cartoonishly large monster and the ridiculous giant rift opening to a parallel universe. I have no idea who Mr. Terrific is but the forementioned Superman films didn't have other random other superheros coming to save superman.
