NO! You CANNOT claim that a movie is still good while acknowledging that! Movies don't work that way!
Actually....you can. And they do, but it totally depends on the person watching.
From my casual study of the movie world, it appears there's two basic, core types of film watchers, both of which are equally valid. Avatar is a pretty good barometer of which type of trait a person has, as it sort of splits them down the middle, as it were.
The first type is the type of person who watches movies as the parts therein. They have separate opinions on most elements of the film, cinematography, writing, character development, special effects, editing, cast, and general direction, plus others. To this person, a good film is that which utilizes all the elements to the full potential. If one or more of the elements in said movie is insubstantial enough, the movie is a bad one. These people tend to enjoy films that would be considered art films, intelligent films, and usually critically acclaimed.
The second type is the person who watches the film as the sum of its parts. While they may consider certain elements of the film, whether those elements are good or bad is irrelevant to them. They rate films solely by whether or not they were entertained by them. These people tend to enjoy films like B-movies, and action films, although not necessarily.
The former tends to dislike Avatar, and the latter tends to like it. I would probably consider myself to be the latter, and I liked Avatar. Granted, its elements were on a whole mediocre, but I was entertained by it immensely.
Hope that makes it clearer.
