The premise sounded interesting so I watched it yesterday and in the beginning I wasn't expecting much since it's cut like a "typical" reality show on MTV or VH1 but I really got into it.
Carne Asada reminds a lot of NOFX, but apparently only had a few weeks to prepare a set of songs for the tour. Sure the songs are no masterpieces but they are fun, even if some scenes were dramatically cut to look more energetic than they were. You will cringe a lot and most importantly laugh a lot.
I also liked the interviews the main protagonist had with bands like Bad Religion, Sum 41, Mighty Mighty Bosstones, Avenged Sevenfold,...
Worth a watch.
