Prison Break started out ok for me but I got fed up with it after while and never carried on with it, the story lines were good but needlessly dragged out. Breaking bad was excellent I thought, watched a lot of it back to back and had lots of late nights but it really sucked me in. "Call Saul", great character, there's a spin off series of him I believe.
Best ever though has to be Game of Thrones, I thought the TV series was good but I started reading the books and realised how diluted the story lines were in comparison. There are 7 books in total so far, I'm up to book 5 part one - halfway through it, they're brilliantly written although book 4 part two was a bit heavy going. There another few books to be published as yet and another couple of TV series to follow.
