Either that or have one villain for each half of the season. It would really solve a lot of problems the show has had with its Big Bads.
They could repeat the DeathStroke trick where there was a lower level villain first. Should make that one a bit stronger, Blood wasn't a real fighter.
Imagine Aliens invading New York again and He has to stop them all by himself, thats how Stupid the whole nuke storyline was.
Where was the CIA?
DoD?
NSA?
Somebody besides felicity to stop the goddamn nukes, I can only suspend my disbelief by so much.
Hint: not in the city where there is not a single nuke located.
