First off I wasn't sure how good this season was going to be, since I wasn't too impressed with season 3. Glad I got it anyways. I was actually laughing alot through this season. On the serious side of Detklok they finally put more storyline to Mr. Salacia (however you spell it) and Falconback as well. There were some repetitious jokes and scenes and that's why the 4 stars, as well as seeming a little short. Overall definitely worth buying.
