Coming only two episodes after the big Apollo 13 parody, "Epidemiology" runs the risk of alienating viewers with another straight parodies. I like these parodies as much as the next person, but I hope that doesn't completely overwhelm the show and the actual community college stuff.
But even if Community goes down the road and becomes a collection of parodies in the future, "Epidemiology" is a great episode by itself. Since Halloween is in three days, it's naturally a Halloween episode, rivaling even last season's Halloween episode. With everyone dressed in various costumes, a real life zombie outbreak happens, quickly overrunning the school.
The episode is a total blast with literal zombies biting things and eventually the entire group getting turned. Along the way, Shirley and Chang sleep together (like Jeff and Britta did after paintball), while Abed and Troy work out their friendship and save the day.
Score: 9.4/10
