I didn't care much for either of the mash-ups, either. As 3C's said, the guys' two songs just didn't go together, and as for the girls... Livin' On a Prayer is kind of Penn State's theme song, I have no idea why it has been so dang popular with the students the last ten years but I have heard it done to death by cover bands and choir groups, as well as played at sporting events and homecoming parades in town since I've been here. But that's just me, others hate Beatles' covers but I actually don't mind those. =p
AND as awesome as I think Bieste is, she totally should have punched Will after the kiss. That was a pity kiss and I don't think she'd appreciate being patronized like that.
Other than that - loved it. I liked the airs Puck was putting on about Juvy, and then confiding in Artie about what really happened there. I like the relationship he and Artie are building.
I like that Rachel barely had two lines. I like that Mike Chang had any lines at all.
I like Blaine. A lot.
I like that Kurt flipped out on the neanderthal, but I totally saw the kiss coming, not that I mind.
I don't like that Artie still wants to date Brittney, but if it is just a plot point to get him and Puck bonding then I don't mind it.
Still, Warblers stole the show. Can't wait to see the old folks sing.
