Yes, Warner Brothers owns the characters of Lois Lane and Clark Kent (etc) and holds the license rights to them, but ABC/Disney and the production company own the show itself.
Now, I don't know that this situation is the cause for any prejudice against the show vs. the other versions, but it is a possibility. Maybe?
Tank (who has heard that Warners is pleased with the movie's performance even if it 'supposedly' didn't quite match some people's expected results because of the known worldwide appeal of Superman and the expected upcoming foreign and DVD sales)
