Meh, track was rubbish, didn't generate much overtaking at all. Very little wheel to wheel racing. Effectively zero good corners for action, it was pretty much single file except for the final straight which didn't seem entirely conducive to overtaking. Such low air density maybe meant DRS or a normal slipstream didn't have as much effect, added to temps meaning cars often went out of their way to not be in the slipstream.
I never care how a track looks from a layout, reality and layout don't often match. People said Sochi would suck as well but it's been great and promises classic races in the future when the cars are more competitive with each other. This track though doesn't remotely work. Some tracks are poor wheel to wheel but still provide some excitement in qualifying. Monaco sucks as a race but qualifying, inches from walls, it's at least good for that. This sucked in qualifying as it's such a boring track and it doesn't lend itself to any wheel to wheel action.
While the atmosphere was great in the stadium that was by a large way the most boring part of the track. The only 'overtakes' were both coincidentally for Perez, no one else came close to an overtake there, one was literally gifted because of an earlier mistake and the other was a mistake going into that section by Max. DIre design of ultra slow, narrow corners with zero chance for a real overtake, it's a procession section of the track and gives a crap sequence into the main overtaking straight.
I don't know if that stadium has enough space there but some kind of german style long straight into a hairpin to have some big overtaking moves just infront of the stands then loop back around the old turn around the outside of the stadium back onto the straight. Putting such a ridiculously awful section inside the stadium... lol.
I can see in the future that Sochi could be brilliant with closer cars, I can't see how that layout in Mexico can provide better racing, it needs a complete layout change.
