Thats not the issue. The point is that Supes has an incredibly distinctive look. No matter how thick his glasses are, Clark Kent is still a dark haired, blue eyed, Adonis of a man with a chin that would give Bruce Campbells a run for its money. I dont give a crap how good his acting is. Hes not fooling anybody. Hes about as convincing as Rachel Leigh Cook was in Shes All That.
I propose that, by your logic, its too much to have an obviously good looking guy in the role. We should have Supes look more average and ordinary so that we can actually believe that he could blend in.
High profile fanfilm is an oxymoron. I respect fanfilms and am glad that people do them, but to act like you can take anything that was shot there, with a shoestring budget and limited creative input, and try to say that its somehow relevant to what you can't do in a Hollywood film is ludicrous.
Lets turn this on its head. Just try and imagine your favorite celebrity walking around your office, with nothing but a pair of glasses to conceal his identity. The very idea that you wont recognize him is completely absurd already, and whether or not hes muscle bound is hardly an issue. The logic of the real world does not apply here.
Ultimately, all this boils down to is whether or not you like the look of a bulky Superman. If you dont, thats fine, since we all have our own personal preference for how these characters should look. Dont try to tell me my bulky Supes is any more ridiculous than yours though.
