On the night that featured both the season premiers of Adventure Time and Regular Show, one show did well, the other had a hundredth episode special that left a lot to be desired. For a show that ended last season with the announcement that Lady Rainicorn is pregnant with Jake's baby (something that the fan community has been calling for for years) they did not do a very good job commemorating the 100th episode or bringing the premier up to at least the par standard established for the show. The story was stock and generic. All I can say is, the Fiona and Cake episode better be good and the Lich story line should at least be continued in a way more satisfying than "Did you get the book?"
It was good, had it's typical funny moments, but for a show as "bombastic" as Adventure Time I expected more from the 100th episode.
