I do wonder whether the poster is expressing a different sentiment than he meant to convey. We all agree T2 is a great movie, and holds up, and is a model for this sort of action film.

Maybe what he means is that when lists of greatest films come out - yes, films, not movies - you won't see T2 on such a list. You might find, say, Lawrence of Arabia on such a list. And he thinks T2 should be right up there with "serious" fare like that. And that can certainly be argued, as action films are conspicuously missing from being treated as film art. It's a guess, as otherwise what he states just does not hold water.
