Just binge watched (over a few days) Mayans MC.
I give it a pass mark. At the start it really felt like it was just Sons 2, but ended up being ok, as the MC becomes is kind of a secondary character in that it kind of builds the frameworks, but the show itself is about the individuals (including the character who are not in the MC), not the club. There are some references to SAMCRO and SoA, but thanksfully they are kept fairly minimal.
There are a few crossovers from Sons. Mild spoilers ahead..... Potter, the weird DoJ dude is in it, as is Alvarez as the Godfather of Mayans (although I find his character fairly uninteresting), and for some reason that is not really explained properly, Chucky, the weird guy who worked for SAMCRO, is now the errand boy for the Mayans, hundreds of miles form Charming. And there is an odd cameo from Gemma Teller is a flashback scene - I was hoping this would tie in somewhere later in the series, but didn't.
I did like the twist in the last 10 minutes of the final episode (which does involve SAMCRO). It will be enough to keep me in for Season 2.
