The very definition of mixed to good reviews. The second movie had lower critical scores, but the audience score remained the same -- in the 'good' range. Box office was much higher showing audience interest, but because the budget was much higher, it was a loss in the theatrical window.
Despite a mixed reception, it has become a cultural touchstone, which is fungible with interest in DVD, TV, streaming, merch, and... park attractions.
Another TRON movie (Ares) has been mentioned. Though, I wouldn't be surprised to see it become a D+ series, maybe animated. (REBOOT rebooted!!)
