Heroes
Heroes is an incredible show with a crappy advertising campaign. Three episodes aired before I discovered it was a show about superheroes, instead of, say, firefighters. The ad campaign is all grim everyday New Yorkers and a dark skyline -- is it any wonder I thought it was yet another 9/11 cash-in?
What it turns out to actually be is an X-Men ripoff, but a really well done one. Instead of starting with spandexed heroes already in the batcave, we get to watch multiple characters dealing with the fact they have crazy superpowers -- and trying to hide those powers so they can keep living life as usual. And then we get to watch them rise to the occasion, and be heroes.
My favorite is Hiro, the very enthusiastic Japanese office worker/nerd. He's just so HAPPY! Seeing the contrast in how his character changes in the most recent episodes really shows off the strengths of the actor playing him.
So, yeah. If you like the superhero genre in any way, shape, or form, and you're not watching this -- you're doing yourself a disservice.
