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.
You could also get an RF adaptor and hook your PS2 into the cable box. (or straight into the TV if it has cable inputs). I don't know if it would be cheaper or more easily found than any of the previously mentioned hardware, though.
