This show sucks to be honest, the problem is that the most interesting shyt is happening on land and we're not seeing it. The show was supposed to be about the outbreak from the start and they glossed over that so quickly, whether it was them living in a fenced off area in LA, or the time jump between season 1 and 2 where shyt really hit the fan and the entire city is burning at the start of season 2.
And the whole Mexico shyt doesn't even make sense, society has collapsed so why the fukk would you need to pay anyone to "sneak" you into Mexico? Like money has value anymore
