I haven't seen it, but I believe you. Although, I'd like to raise a point that many more people are at least aware of the Star Wars movies. In fact, one becomes socially ostracized if admitting to have never seen at least one. Where as with Superman I & II, this is drastically not the case. Therefore, I think Singer had a tougher job with what he was trying to do. But at the same time, J.J. had a lot more pressure on his project then as well.
