I think this spidey series is really good (the second one was especially good). But I was wondering exactly how many spidey movies can they make. I mean these actors and actresses can only play college aged kids believably for so long (Tobey Mcguire is already in his 30's I believe).

As long as they continue to make good stories and plots in these movies the interest will always be there. But will the believeability continue to be there if they make more than three of them.
