That was kind of amazing and I was really impress. It was the first time I watch this show. (I sometimes watch partial episode in French but that was crapy) I really like Tina Fey so I've decided to give this episode a go and I was not disappointed at all. The live performance was really nice and give a lot of rhythm to the show. Julia Louis-Dreyfus playing some parts of Tina Fey character was funny.
For the story of this episode compare to the whole show I won't give any opinion because I don't know this show at all but I had a really good first impression!
