I desperately wished to enjoy it, as HBO offers so little at this time, but I was bored senseless and couldn't make it past the first episode. It has such an odd tone that makes it seem like an episode of Barney the dinosaur. Another reviewer likened it to Dr. Who, and that's pretty accurate.
The good news is that with Game of Thrones gone, there is really no reason to pay for HBO when Silicon Valley finishes this season.
