When I first saw him in Silicon Valley I thought he's so incredibly talented, perfect delivery of his lines. You could tell he poured a lot from his own personal style into that character and I appreciated that immensely. In Deadpool he was also pretty good, reminded me of his Erlich Bachman character a little bit, but that was a welcome reminder. And then I watched this... "special".
My initial conclusion is that he should absolutely, under any circumstances, not write his own material. His special is rife with juvenile, stale jokes and word play, obscure references that are near impossible to relate (and I enjoy comedians from Hart and Rogan all the way up to Louis CK and Lewis Black). His delivery is good, he's a talented actor, but the material is extremely stale and obscure. As if it's almost improvised on the spot, very poorly. Near the 20 minute mark I was visibly waiting for it to be over.
I think the most fortunate consequence of watching this thing is that the beloved character of Erlich Bachman is untarnished. If he ever makes another special I will not waste my time again unless it comes extremely highly recommended.
