I liked it. I have never understood the backlash against the ZH cliffhanger. The Alien Nazi reminded me of Red Skull and I was intrigued by the "Archer out of time" aspect. I thought it did a good job at piquing my curiosity with who the alien was, what was happening in the past, how it played into the Temporal Cold War. I also got a kick out of the bizarre sight of WWII fighters firing upon the shuttlepod.However, the season-ending cliffhanger with the space Nazis made me want to put my foot through the TV. We waited a season for space Nazis?
In fact, the teaser was so open-ended, anyone with a creative mind could have developed it into a potentially entertaining storyline. The problem was Coto who did the most bland story he possibly could have. So I don't fault B&B. I fault Coto for what he ultimately ended up doing with it.
