Both can't touch LOTR as they became overrated as time gone by I say Avatar as it took me longer to consider it overrated. People say HP7.2 is the best and I don't get this shish when Prisoner and Goblet is still>>>>>>>> ur fave potter movie...It's probably because after it sank Titanic, Avatar became way overexposed with all the hail Avatar, full of graces praises and hype that no other movie can match until maybe, the next James Cameron movie. HP7.2 Both movies can't be called terrible. They're both decent. So people calling those flicks bad are delusional or they're just hatin, but no one can call them modern masterpieces, but Avatar probably has that longer end because of the prestige it garnered after beating Titanic and almost matching its boxoffice gross even through adjusting for inflation.
