I have two minor problems with USM. They're not really faults, but more or less quibbles.

Firstly, I really wish Spidey could do the Yo-yo move. Just like in the first movie game. I miss that.

Secondly, I like walking off buildings and holding the wall-crawl button down so he'll immediately start crawling down the side of the building. BUT if the building has a ledge or a lip / barrier, forget it. You can't do it. I wish the software developers had made it so he could do it somehow. You can always jump over the barrier and then quickly turn and grab the side of the wall, but sometimes you grab too soon and he leaps back over the ledge to where you started. Annoying!
