This is one of those series in which you get a wonderful premise, at the start is well executed, nut then after a certain point everything falls apart. Which makes it very frustrating, is it good?
Well...yes, if you see it you will certainly get a lot from it. It introduces some principles of quantum mechanics in order to serve as a main plot engine, to deal with parallel realities, and they are presented competently at mostly accurately, thus in addition to be entertain you'll learn something, and all goes great for 60% of the duration.
Then it introduces some twists and revelations that do not get explain and do not make much sense and the show suffers the rest of the time for them, and by the end you feel it could have been more.
