In a nice change of pace, To Catch a Pokemon Smuggler! gives Team Rocket a break by filling them in with a bad guy substitute: Dolan. A Pokemon smuggler, Dolan poaches and smuggles Scatterbug and Spewpa and sells them off for big bucks once they evolve into the beautiful, multi-patterned Vivillon. This was a well-structured filler episode that did not necessitate the Pokemon anime's traditional "character of the day" to drive its plot--rather, Dolan is this week's villainous guest and our heroes take the initiative to halt his criminal deeds. The characters' traits were used effectively, with Serena using her fashion skills and Clemont coming through with an invention in order to advance the story; these kinds of progressions that necessitate certain characters' skillsets are always welcomed, as the Pokemon anime has received largely-deserved criticism in the past for the staleness and lack of development of its characters. That said, the episode's dialogue was pretty weak this time around. Most of the characters spoke in tiresome, bland cliches, which came off as unnatural. It was also disappointing that Dolan was really nothing but the cliche bad guy--no personality traits other than that he was indeed "bad".
Nonetheless, I would call this a lightly above average filler. The characters were used effectively--albeit, they didn't articulate their lines all that well--and the writers gave us a different villain for a change. The humorous highlight of the episode was Ash's obtuse, feeble-minded explanation of Pokemon evolution to a curious Bonnie. Still, the episode's overall execution left much to be desired.
Grade: C+
Side Note: We sure are seeing a lot of Officer Jenny early on in the XY saga, aren't we? Wonder if that trend will continue as the series advances...
