Critical reception
Alisa Simon from Variety wrote : "A rallying cry for government and collective action, H2Omx is a good-looking, well-researched and smartly assembled documentary that makes a persuasive case that the time is nigh to remedy the status of water management in the Valley of Mexico." Josue Corro from Time Out México wrote: "H2Omx does not try to find solutions, but to raise awareness about the future. The honest way of dealing with a problem –without political charges, or sensationalism– places this documentary as a work that goes beyond the genetics of school or television documentaries, and projects it as an informative and relevant film on the history of Mexico City."
