Didn't care for this episode to be honest. The whole frizzy hair gag has been done to death so I just cringed when Oak's hair got all static-y due to Rotom. I liked the junkyard setting for most of the episode, but the whole "Rotom can enter appliances and cause havoc" thing has been done before and better imo, so it wasn't a completely original story line. I did like that the group used their Ground-type Pokemon to their advantage though. That was smart. As for Oak catching Rotom; it seemed redundant since we're not likely to see Rotom all that often, but whatever.
