Finally had the time to sit down and watch the most recent episode, definitely the best yet, and I can say that in my mind, the series has crossed the hump as to whether or not it is worth watching.
In that sense there's quite a tough challenge, as anyone from the comics would mostly be a "huh?" to someone like myself, but anyone whose just from the show will make all the comic fans somewhat disappointed (reading a forum past few days, there is typical nerd rage from people who wanted more named supers in the show, although it's receded a bit since the reveal NP posted above). My early theory was 'The Leader', the scientist from The Incredible Hulk (someone I only learnt about after watching the film and wondering what happened to him).
