I was bored, so I watched the Sunny/Abbott crossover. I'd go 6/10. They did about as good as they could do with the amount of characters. It was a bummer though that Dennis is only in it for 30 seconds, as Glenn Howerton was filming a show he is doing with Kevin Bacon. Apparently on the Sunny side of the crossover which is airing sometime this year, we will find out what Dennis was up to.
The Dee/Janine/Young Chris Rock (Sorry, can't remember his AE character name) storyline carried the episode hard and was awesome. All three characters played off each other greatly, and the height disparity between Kaitlin and Quinta was absolutely hilarious. I think there's a foot height difference lol. Every scene was a delight and they need to find a way to get Dee another guest spot on Abbott maybe getting a Substitute Teacher gig or something. Kaitlin and Quinta were so good together. Shame the other three storylines didn't live up to that.
The Mac storyline as usual was the worst part and a waste of time. Frank/Old Man Janitor didn't really do it for me either. I liked the Charlie storyline and found it about as cute as you can get for Sunny.
