It's another episode of AD that can't touch the masterpieces from earlier this season.
There were some funny bits, like Stan and Steve shilling random products. And Roger wanting vengeance over a roast was awesome and perfectly in character for him (ditto that for Stan fleeing to the escape pod instead of saving everyone). But this one just felt a bit off.
Kind of a groaner, much like Steve's "my momma" joke.
I thought the roast portions were great as well as the CIA/Chia Pet stuff. Patrick Stewart just kills as number one. I felt like they already did Alien(s) before, but it was just good for the final roast. It was better then last week's episode that is for sure. I thought maybe they should have gone on longer with Roger trying to kill them instead of doing the Alien(s) send up, but whatever the payoff was good.
I don't want to be mean about this, because I love Community too, but I wish the internet would've stop having a coronary every time a well regarded but low rated show gets moved around or put on hiatus.
