Just watched the both East Coast and West Coast versions of the show. If you only see one, I say watch the West Coast version. It has a couple better rewritten lines and a couple minor, unplanned gaffs. Also, there's this neat list of the
17 Differences between each version. Pretty cool.
Did I like the ep? It was much better the 2nd time once I fully understand what they were trying to do. But the SNL atmosphere was very surreal and reminded me why 30 Rock (and most other sitcoms) work so well without a laugh track. Took some getting used to, but, for the most part, I'd say enjoyable (esp for a couple surprises here and there).
