They are really wayyy too different...A better question is if you HAD to cancel ONE of the two which would it be. Season 5 and 6 of 24 are really good IMO...Hereoes started off with TERRIBLE acting but now I'm hooked....OMG I can't choose!!!
Heroes might be good and all that, but it's no 24. I mean, the public has spoken, and it seems they agree.
I don't watch Heroes... am I allowed to vote? it will be a biased vote if I do. But oh wait, the results ...
