Two episodes in for the HBO series Luck and many critics abound, calling it slow, boring, hard to understand, etc.
Maybe because I'm a David Milch (creator of Luck) fan I knew to expect slow character development. I loved his Deadwood series on HBO but watching the show took dedication to the many plot lines and story telling. I'm also a big fan of HBO's series in general, and a lot them also took time. Remember how many times you watched a Soprano's episode, and complained about the lack of action and confusing endings? And how many people missed the brilliance of the HBO series The Wire because they bailed early, confused by the many characters and plots.
These type of shows take investment of time in exchange for a build up and subsequent payoff. Yes reading tweets on twitter will give you an instant payoff but sometimes wading through a long book is worth the later payout.
