IMO this is a disappointment after Breaking Bad, which was always going to be most likely anyway, as Simon states at the beginning of his review.
The best episode was the one revolving around Mike and his relationship with his son and his son's wife.
The character of Saul Goodman worked so well in BB because he was a part of the general BB craziness and tension and conflict but as a main character carrying the show he is too one dimensional and predictable.
The script writing is simply not up to the exceedingly high standard set by BB, which is not surprising.
Breaking Bad = 10/10.
Better Call Saul = 6/10.
Hopefully it will improve in Season 2 but it needs to do so very quickly, IMO.
Personally I thought this was brilliant!
The scams he had pulled in the past were hilarious and some of the scenes in the last episodes were gut wrenching and totally convincing.
I really cannot fault this at all, But then again I did not go into it expecting breaking bad.
