Heroes
Heroes is a show about people all across the world who discover that they have extroidinary abilities. From Issac Mendez, an artist who can paint the future; to Hiro Nakamura, a Japanese desk jockie who discoveres the ability to bend space and time; Claire Bennet, the indestructible cheerleader; and Sylar, a serial killer who targets other people with special abilities. They all come together, they must learn to use their abilities, and eventually, save the world.
Yes, I know it probably seems like I'm talking about X-Men, but trust me, this is no X-Men rip-off.
If you choose to pass on this, then you're missing out on what very well may be the best show on TV. There's plenty of special effects, and most are movie quality. The first several episodes are pretty graphic, such as the cheerleader waking up during her own autopsy, or someone's head being telekenitically sliced open so that Sylar can steal the brain (no I'm not kidding), altough the later episodes aren't as graphic because NBC caught a lot of flack for putting graphic violence on primetime TV.
Along with each episode that was shown, was a four to five page graphic novel (comic book basically), that usually fills in the gaps in the story between episodes. They also have on their site interviews with the cast and crew, full episodes with cast and crew commentary, among other intresting things.
If you watched it, let me know what you thought of it. If you didn't, you really missed out but can still watch the whole series (well, the first season) on the website, and you'll be glad you did.
