I actually like Superman Returns a great deal. I liked the movie when I saw it in the theater and I have watched it over and over on DVD. I actually like this version of Lois much better than Margot Kidder's version.
I didn't care for the stalker scenes and it could have used a bit more action. I actually like the Superman-Lois-Richard triangle and the fact that Richard was a good guy.
All in all I do like the movie despite its flaws.
