I stopped caring about him in the movies the minute they totally screwed the reunion between him and Sirius in the shack in PoA anyway. That whole scene in the book was the reason I cared about any of the Marauders at all. The movie didn't come anywhere close. But then, movie-wise, they screwed all of the stories. I couldn't care about any of them in the movies.

The same goes for her. She was just there to have cute hair in the movies. Blah.
