Apparently so. The Last Airbender, the live-action movie based on the Avatar: The Last Airbender animated TV series, is supposed to be part of a trilogy.
The first movie is in theaters now, while the next two installments are to be filmed one at a time. According to the article, "Last Airbender Trilogy Not Being Filmed Back-to-back, May Take Over 6 Years to Complete," on slashfilm.com from July last year, M. Night Shyamalan was still working on the script for the second film. This seems to support the idea that The Last Airbender is the first of a trilogy.
Finally, if you see the plot summary taken from the official movie website for The Last Airbender quoted further down this page, you’ll see that "‘The Last Airbender’ is the opening chapter in Aang’s struggle to survive."
So, yes, The Last Airbender is a trilogy.
More recently, critics have knocked the film heavily, giving it bad marks for any number of issues.
TV series viewers have done the same, but I always discount those kinds of reviews, simply because I know I don’t enjoy a movie as much if I go into it with expectations set by a book or television series I’ve loved.
I have family very interested in seeing this film. As someone who has watched bits and pieces of the television series, but not enough of it to have expectations about the style or content of the movie, I would also like to see this one. The Last Airbender looks quite appealing!
