How the fuck is The Sopranos overrated? You obviously haven't watched it from start to finish if you think that. Not only did it set the standard for premium television but it also had excellent writing, an excellent cast and despite what anyone says about it, the perfect ending for the series. Did it suck to watch live? Yup, but after repeat viewings it starts to become much clearer. You can't say something is overrated without giving reasons, otherwise you just come off like your trying to be the cool guy that has the different opinion.
I also don't know how you can watch one episode and decide you don't like it. The length of the show won't be an issue once your a couple in because you will be hooked.
Sopranos isn't that long. Lost and 24 are waaaaay longer due to broadcast tv seasons having at least double the episodes.
