Oy, let's not start that debate again...
Yeah, I was wondering that myself. The grimace/scrunch on his face almost says "Yeah, I wish", or "If only". Perhaps it was to say that he didn't want to go on the date with Miss Piggy?
I've been thinking about this production as a whole today, and, of course, I'm excited. I know a few fans may detest the use of Walter as the main character, but, if they play their cards right, I think this show can do loads for him as far as character development goes.
As of late, fans have started to have a mixed reaction towards Walter, mainly his role in MMW. They've been saying things like "Scooter could've filled in his part just fine" or "Was there really any purpose to his appearance?". Now, I don't necessarily disagree to these things. But, Walter is in the beginning stages of becoming a character. I think the writers are still trying to figure exactly who he is as a character. Sure, he's a muppet fan. Sure, he's nice. Sure, he can whistle.
But, that's just about all we know about him so far. I hate it when one of the few words you can use to describe a character is "nice". That's one of the most generic words you can use. I think (and really hope) that this web series can do good things for him. Give him all kinds of traits and quirks, really make him a part of the Muppet family. Then, I hope, he'll be less Scooter-like, and become his own character. Then, they can start downplaying his roles because they've developed him as a character. Win-win situation, really.
As for fans who detest Pepe...sorry. Really nothing I can do for ya.
