Spoiler Level: HUGE
YES!!!! Yes, yes, yes, yes, a thousand times YES!!!! They had it all set up, they had Clark all ready to tell Lois the truth about himself, and they played it in the total Smallville style-- by the end of the episode Clark now had a million "very good reasons" to change his mind by the end of the episode and tell her "Never mind." They even had me believing they were going to wimp out again. And then Clark goes and does it! WOO-HOO!!!!
It also shows how the concept of Lois & Clark as a team, with Lois knowing who he is, has become such a strong part of the Superman mythos that they felt it had to be included before the series ended. Which so totally, totally makes me happy.
Not to mention how cool it was to have Isis back on TV for the first time since 1977. I also find it cool that this TV version of Isis is based on the current comic book version of Isis, which in turn was created as an homage to the original TV version of Isis featured in the The Shazam!/Isis Hour TV series, who was actually created by Filmation. TV imitates comics imitates TV. You gotta love it.
One odd thing about the episode: Clark comes up with the new Blur costume with the red jacket, and then runs around doing total Blur stuff without changing into costume in this episode. Why?
Cool fanboy moments: The Dagger of Teth-Adam was a real thrill, and the yellow energy ropes made me giddy at the taste of what a live action Green Lantern Corps/Sinestro Corps battle would look like!
