When this ep was kicked off with the Jellyfish thing, I really didn't want to like it. I was prepared for another boring and uncohesive fest that shamelessly plugged various guest stars.
But that's not what was shown. This ep was very solid in plot and didn't go too crazy, and had quite a few good jokes.
I don't understand why people think Ned was out of character, though. It's not like he completely voluntarily gave himself to the actress.
One of my favourite bits was the John Williams concert. I recall the use of a John Williams concert being done in an earlier ep this season, but this time I found it really funny. Aside from Homer and the recording being recycled...
Anyway, this was an all-around good ep. As I watched, my score went from 3 to 3.5 to 4. So... yeah, 4/5 from me.
