Nah, there’s no pop culture footprint there like your Star Wars, potters, marvel, etc etc etc. Anyone who says otherwise needs to find the huge merch, spin off, multimedia, extended universe, cosplay, and conventions that don’t exist for Avatar or call it a day trying to keep this pointless argument up. It’s beyond tired. They are movies people tune in for, not pop culture things.
And I’m the one who called A2 being a box office juggernaut when very few here did that first week of release, so I hardly need to be reminded about success metrics.
