I liked the new designs for most of the character.
Brainy looked more mature and a little older which I found was a good move.
Also ,Lightening Lad's new look made him seem as if he'd grown up considerably and his usual hot head self was gone some what.
But that aside I found this a little furan and for some reason I missed the real Superman and found that his clone didn't cut it, though I think that's what you were supposed to feel.
With the added bonus of a new villain that I'd never see before, it was a little crowded, even though not much really happened in it plot wise.
With a goal of bettering Sundown,it never really had a chance, but it's an OK episode.
