Heroes is my most favorite Live-Action TV Show ever
Season 1 is the best, season 2 is where Sylar got depowered, Season 3 is where Sylar got all new powers from his new killing spree(Claire Bennet is only one that survive this) and the part where Hiro and Ando are offered to be villain is where Heroes stops canon for me(among other reasons, Arthur Petrelli powerdrains Hiro Nakamura, seasonal rots, lack of alternate futures, and so on) where 4th season of Heroes is the breaking point of the original show(Sylar got mindwiped to have his body used as Nathan's new vessel comes to play on making this show's seasonal rot that become straw that broke camel's back)
and Heroes Reborn is failed revival of Heroes tv Show
