Yes! Yes! A thousand times Yes! I hate constantly mopey superheroes. Batman is not worth watching (to me) unless it is a fun Batman (Lego, Brave & the Bold)
The scenes I remember most are the fun ones (Wally griping about girlfriends, his hair, making humorous quips often about his own f-u moments. That is the Wally I loved as much as his doing awesome feats. The Wally who messed up and had to go back and switch Christmas gifts last pico-second as the recipients opened them. Friendly, slightly goofy Wally....but not as goofy as in the animated show. I really, really, liked animated Wally, but he just introduced me to Wally's Flash book....which is when I fell head over heels for him.
I would love a 2016-Rebirth-era story where something weird happened and we got to see Wally and Barry's take on it. Something on the order of those crazy sentient clouds of Silver Age Barry. I can see Wally kind of going "Huh." Then shrugging before doing his things with quips about (if I insult it will it result in a downpour?) thrown in. Barry meanwhile would start going all scientist on them. (Don't be ridiculous. *goes into weather science flash facts* while Wally ponders flood insurance.
