The first season was absolutely great. We had some great what if scenarios & some Really good stories. Unfortunately it started going downhill.
The second season was still watchable but the third season makes me wonder why did I watch it?.
The ending is absolutely ridiculous. So you just become a watcher by repeating an oath. There is no explanation as to how piggy defeated three Watchers and their combined power? How was she even able to move them to a different universe when Kanhori couldn't?.
The watches are 5th dimensional beings. The power is above any universe so how was Stephen strange able to control their power?
The only good enough episode was a one with the red guardian.
