I personally wish that the TPCi dub of Pokemon could take the Digimon (Fusion) dub route of adding a sense of cattiness and humor while not going too far. Honestly, the Anime's pretty bleh nowadays that a gag dub could only save it.
When given the characters a sense of cattiness in the dub, it helps to make sure it's in-character enough to work and they don't go too overboard if they want to maintain the spirit of the show. I don't mind it since the characters can lampshade the weirdness going on. I find it fun when a show can take itself seriously yet know when to acknowledge how bizarre it is and have fun with it.
