Eps 1-3 could be hard going for some (but others will enjoy 'as is').... but when you have ep 4 under your belt, it all comes together.

If someone has seen ep 4, pay attention; if not.... look at another review.

For what its worth, I have watched 1-5 (5 was released today) and I am annoyed I can't get to Ep 6 yet!
