I can't imagine how long it took to put this show together. This series is about interdimensional traveling and alternate realities. The first season is on the edge of not being understood. Perhaps it's because I have a very picky interest when it comes to sci-fi. The second season is very complex and mind bending. It introduced a second story that then comes together with the first one to simultaneously solve two mysteries, if you will. Although it's not my type of show, and so far I'm only on S.2 E.7, I can tell you that the type of mind to have put together such a story had to have been a genius one. Lots of turns and curve balls. More than anything, I found it to be very weird and an odd way to explain and try convincing the audience of the theory of a multi dimensional universe. However, I do recommend it for those that are into alternate realities and interdimensional traveling. Also, the series is very much built on drama.
