The first hour, for me, was just meh. Good music, but the episode didn't have very good flow at all. Even though it added to the odd pacing of the episode, I'm glad that the swap segment was as short as it was. It was good as a one off joke, but I think a whole episode of that would've been way too over the top. Some of the swaps were inspired (seriously, who would've thought that Darren Criss would make that good of a Puck? Or Harry Shum Jr. pulling off Joe's dreadlocks?) and some were just WTF (What kind of drugs were they on when they made Kevin play Brittany?). The second hour, though... very, very good. Although, was I the only one who thought it was a little too fairy-tale ending, almost like you expected it to be one giant dream sequence? I mean, having Carmen Thibideau show up, them winning Nationals, the whole school (including everyone who hated them) suddenly congratulating them, and Will Schuster go from being a rubbish Spanish teacher to Teacher of the Year? It was a bit much. I did like seeing Sue singing along with the New Directions as they perfomed "We Are the Champions." I'm not sure I can swallow the total about-face they did with Sue this season, sending her to Character Rehab... but I'm glad they did it. Having a likable but blunt Sue is so much better than the hateful Sue that we had for so long. We're back to the Sue that I liked when she was briefly principal.
