My highschool always did a project in the last year before graduation about the justice system: in my year, we visited a jail, talked to people from an organization that helps convicts rehabilitate, another organization that helps the victims, attended a trial. It was one of the most interesting school projects we did. Why am I writing about this? Well, a few years before I started highschool, the teachers had decided to invite a convicted serial killer to the school for a talk and a questions and answers session. Throughout my highschool time, four or five of our teachers choose to tell us about this experience. You wouldn't believe how insightful it can be to listen to your teacher talk about that time they met a serial killer. There was the version of the story that pointed out they made sure the male students were seated around the female students and that focused on the tension in the room (the victims of SK were mostly prostitutes). Another teacher talked about how charming he was, and how she still wasn't sure whether he really did commit all of the murders. And eventually felt the need to point out "but don't you think I had a crush on him". Another teacher actually gave him her address "in case he ever needed anything".

Anyway, yes, I think Community got the whole attractive murderer comes to a school and charms everyone right. I actually really liked that aspect of the story and wouldn't have minded if instead of the party-plot we would have gotten a Britta/Annie/Abed plot that involved (another) convict.

That said, I didn't really care all that much about Jeff's role in the plot. I never liked teachers who show videos in class (even when they are related to the subject) and didn't Jeff claim he actually likes teaching now. I never thought of him as a good teacher, but I never imagined him quite as bad. Just how little efforts he puts into his class kind of cheapens his claims he cares about Greendale now. This season has too much Jeff/Dean. I hope we will get some resolution for it soon, rather than get more of the same. In my eyes, the Dean, just like Chang, works best when his role is small.

I liked the Annie/Abed/Britta plot a lot more on second viewing. I liked seeing that living with Abed can be difficult sometimes.

All in all, it's my least favourite episode of the season. But it did get better on second viewing.

to answer the questions:

1. 7/10
2. The end tag, I guess. There wasn't anything I found really memorable.
3. I'm one of the people who hoped there would be a Harry Potter episode this season because the writers have been tweeting about a "broom episode" and Diane mentioned "a Hermione cameo". Looks like the Hermione cameo was the wand making class from episode one (or Abed's shirt from the second episode) and this was the broom episode?
4. I always liked how we got different character pairings every episode. They don't seem to be doing that so much this season. I wish we'd get more Jeff/Abed, Jeff/Britta and Jeff/Annie. I know that splitting up the cast in "Greendale staff" and "Apartment 303" makes sense for some stories, but I miss plots about the study group with Jeff as the main lead.
