It seems like season 5 is mostly a pretty popular season, but yeah I was disappointed in the number of comedy filler episodes in the first half of that season. I guess that they never had the budget for it but, after all the build-up in season 4, I was anticipating an actual post-apocalyptic season along the lines of The End episode. I was a bit bemused when the world basically remained the same, and they were going to hotels for a SPN convention...
