I honestly thought this week was going to be drek. In an earlier episode, they showed the Amulet of Isis, and I knew they were going to go ‘there’: That absolutely terrible Saturday morning show ‘The Mighty Isis’. They were going to do a show on it… and I knew they were going to have Lois wear it and become Isis. That is the exact kind of crappy idea that ruined most of the previous season’s pacing and tone. Dumb filler episodes.
However… They pulled it off and made it one of the most memorable episodes in the series.
This is a comic book show, so outlandish ideas are par for the course. The good news is they did it with seriousness and a good dose of the actual Isis mythology, which tied into the character development with each of the principles of the show.
Oliver, Tess, Clark and Lois: each one is traveling in their own story arc about managing great love with personal fulfillment and growth… and in the case of Tess (and Alexander, the child clone of Lex Luther)…redemption.

Oh, and the ending was just about as good as it gets.

This, the last season of Smallville… is damn good.
