It'd be detrimental to the world they created, in my opinion.
Yeah I think it'd be fantastic, as I don't think they'll ever make Supermax so why not adapt it as a season story arc. Would be different from the norm aswell to radically change the scope of a series like that. I think even if it was for something like 10 episodes would be good too or even a TV movie.
Sort of like Prison Break, but with DC characters.

Haha yeah
Think it would work really well especially in the Arrow universe.
How did Merlyn train as an archer in the comics? Was there something that made him "evil"? Or have they copied the Lex/Clark dynamic by making him a friend before a foe?
Oh man, yeah that's not as cool now that I know it's a Smallville rip off.
Let's hope Arrow can pull off Merlyn's transition from good to bad better than they managed Lex's turn (albeit played beautifully by Rosenbaum).
Merlyn isnt anything great in the comics so its not a big deal.
Isn't his story along the lines of challenging Green Arrow to an archery contest and losing. That's not exactly riveting television.
As for the Mansion, who cares, its not a big deal, they are filming in Vancover.
The family dynamic works in the show, not everything has to be like the comics, which IMO have been less than stellar besides Year One and Long Bow Hunters.
If he was a loner with no one to interact with the show would be boring.
Do you think the story on the island is gonna be stretched for as long as the show runs or will it be kept within one or couple of seasons and what what do you think will be the new side story be if it that's the way the show goes?
