I've read many reviews about the series, some people are euphoric, some some thought it was painfully bad. It is a matter of view:
When you watch the series with the expectation of a series that is very relevant to the historical facts and the life of Leonardo, you gonna have a bad time. The series has almost nothing to do with the life of the young Leonardo Da Vinci, except for some inventions and the characters who lived in that time.
But when you like a series that is with a wonderful story, action and good acting it is a fine series to watch. The cinematic are fantastic, the story is touching and the cliffhangers are astonishing. If you love Game of Thrones (it is not as good as Game of Thrones, else you'll get your expectations too high) and you don't care about the inaccurate facts, you will like this series.
