The idea of Blake and Yang having a showdown together against Adam is in and of itself a fine idea.
But the actual execution is garbage and a waste of Adam as an antagonist.
The crux of the issue is that this was done too early, at the wrong place, at the wrong time.
I'm probably one out of four people who believe that Adam's villain role should end where it began: Atlas. He should've left with the rogue gallery in V5 (and it really looked like he followed them), he should've aligned with Salem, and he should have went to Atlas next. Basic symbolism in the making, yet the idea was executed early, which is one of the easiest mistakes made in the series so far.
