You've no doubt of course heard of the TV Series called Dexter before, even if you haven't ever watched it. This is, one of the best TV shows I, and a lot of others have watched. Dexter is a show that aims to keep the story moving - every episode will advance the story further without many side stories getting in the way. In the beginning seasons you may see some of Dexter's past, showing how he grew up to be who he is.
But what is the story about you ask? Well, Dexter, the main character (obviously) is a serial killer, with a twist - he only kills those deserving it, such as murders. Interesting, right? But there's also another twist to Dexter - He works with the Police investigating murders as a blood spatter analyst. To add to this, he also tries to maintain a family. As to be expected this leads to Dexter having a busy schedule, which sometimes can lead to suspicion, and mistakes which makes some extremely tense scenes.
If this still doesn't sound interesting to you, some how, you may be intrigued by the way the characters in Dexter are portrayed. Don't get me wrong, some are a little weak and annoying at times, but most are very strong and interesting characters. Dexter is portrayed in an extremely interesting way, where he can sometimes get frustrated if he doesn't kill someone and some other things that I'll let you find out yourself. The "big targets" of Dexter are awesome too. They're all extremely awesome, with some being extremely weird, to some being extremely twisted. All this starts right off the bat from Season 1.
I'd love to say more about the show, but I'd rather you went and watched it for yourself and see how events play out.
