Au contraire, I liked it. Jonathan, who is so not among my fav characters, was very funny and interesting in this episode - it was his 'bright hour'.
Also, Buffy was so trying, so confused... When I watched this episode for the first time I went: 'What's up with Buffy? Ain't she supposed to be a 'superhero' already? What's with theese wrong moves?", but then.... Mmmm... And Anya.... 🙂
On the other side, The Monster was pretty cheesy. Well, maybe he reflected real Jonathan's pathetic lifestyle. Don't know.
Face it, the "Superstar" was quite entertaining episode. It had "its own fun". I do include it in my rewatching list.
