First two seasons were ok but after that donโt waste your time, especially the fourth season. It just keeps getting worse and worse. It was such a great idea and a very interesting way to look at the world and thenโฆ time travel and multiverse stuff happens it just gets stupid. Amongst many other things the 4th season. Itโs so bad I actually forgot there was a 4th season but itโs terrible. Do some bird watching instead.. for real..like itโs so bad Iโm mad I wasted my time watching it. It ended up being one side of America was white people and the other side not. The show started off so good and just did the same thing every other show does when it gets past a couple of seasons.
