No, it's not emo Parker or his symbiote-enhanced jazz skills. It's this bit of pointless silliness:

It was kind of cute when Stan Lee started turning up in the backgrounds of movies, hidden amongst a crowd. It was kind of a game to spot the Stan Lee cameo, like a film version of Where's Waldo.

But this is so prominent, corny, and over-the-top that it interrupts the flow of the movie. Here Stan Lee goes from being an anonymous face in the crowd to playing himself, commenting on the movie in progress.

Enough already!
