I think it's sad because Spider-Man 3 is bad enough to warrant such a poor score, not that I think it's sad because people are being too hard on it.
But I'm not going to get into that.
I was entertained while I watched the flick, I'll give it that. I enjoyed the action, and it was indeed Spider-Man. It's just too bad that much of what entertained me, it was in a way that it wasn't meant to be.
