There is absolutely no doubt in my mind he would work as a villain onscreen. I'll even go one step farther and argue that he does not require the use of a primary villain to be effective.

The trick is how you have John Corben/Metallo and Superman play off one another. If you develop *write* the dynamic between the characters intelligently, then it makes for a very powerful, emotional, and heartbreaking story.

I wouldn't go so far as to say that the fighting sequences would pack as much potential heavyweight action as a Zod/Superman slugfest can feature, but very close, where the difference is negligible. The biggest difference of course, is that Metallo cannot fly, nor is he a military strategist. Still, a very nice villian for Superman to confront nonetheless.
