Thought this episode was excellent - from the relationships (Chole/Stewart, the Oliver/Mia, Tess/Mr Zod and of course Clark/Lois) to the introduction of the Luthorcorp Towers as featured in Lois's flashbacks. It's nice to know that the story is still winding along.
The only thing that puzzles me is where was future Lois when current Lois went to the future? Possibly not the place.
This series has enjoyed a few comic storylines but I think this episode was necessary to clear the air a little and to get the characters moving on - don't get me wrong, I thought the end was superb (and long overdue) - but hopefully now we can settle in for some serious action.
Bring it on!
