My only quibble with this episode was how hard Thanos jobbed out. Though given what the premise of the episode was, I'll deal.
This episode could have had real pathos to it but, it kind of undermined itself with the jokes. That said, The Watcher's reaction to his situation was funny ( but I can't be sure it was intended that way).
I kinda hope part 2 will be longer but I don't think any episode has gone over an hour so I'm not expecting it.
