Watching this because a friend said "remember walk the line? It's that again, but with different jokes. They are exactly the same" and you know, I can't really see any flaws in that.
Also, I love Radcliffe. He took all that Harry Potter movie and decided he would just do whatever movies sounded the most fun budget, potential for success be damned. Period ghost story? He's your brooding noble. Dark gamer comedy? Sure, bolt guns to his hands. Need a farting belching corpse? He's got you covered.
