That was a whole hour of nothingburger outside of making High Pitched Homelander Jr. start down his path to evil. The episode wasn't even clever gratuitous violence (outside of, maybe, Hughie's advertisement for Euthanasia). Instead we got an hour of retarded writing so they can try to make jokes with farm animals. In trying to not be repetitive in their gore, they are becoming repetitive and boring. Oh, some red shirts are going to die, wow, soooo exciting... reminds me of the Battle for Winterfell in GoT S8.
For the farm in particular, the blood was still red, and everything looked fresh, there was no way the whole farm got infected in such a short time, even if I bought into their stupidity that a drain under a basement, somehow drained directly into every animals drinking water.
Also, the vampire sheep were pants on head stupid for a whole host of reasons.
