Everything involving Cas learning with dealing his new humanity is absolutely wonderful. It is funny, endearing and just quirky in the way the show is. I don't even mind that the writers got him into a sexual situation basically as soon as possible. I love the angels being the early villains in the season and the Buddy Boyle aspects have a nice anti-clerical that the show sometimes has.
But BOY are there two really forced plotting choices that weaken the episode. First, I am pretty sure the writers decided to turn Reapers into a class of angel-out of left field and against 8 prior years of text showing reapers to be a different faction, beings than angels or demons. This gets much worse later in the season when a Reaper is explicitly said to be an angel. Second it is unbelievable that April found Cas and the brothers found April in the time they did.
