The Last Airbender 1/10
Nope, I'm not even giving this movie the dignity that I gave The Room by pretending it was any good. Nope. Nope, nope, nope. This film can go burn in hell. Actually, I'd bet that they play this movie on a loop in the waiting room of hell. It would be more than enough to make Dante cringe (Alighieri or Basco; the reaction's the same either way). I knew going into this that it was going to be gut-wrenchingly bad, but . . . wow. I don't know what happened to Shyamalan over the last decade or so, but he's gone from being a unique and captivating storyteller to arguably a worse director than Ed Wood.
For the love of all that is good in this world, do not watch this movie. Whether you are a fan of the excellent, excellent cartoon series this movie is based on or not (and I am, which only made this all the more painful), The Last Airbender is simply not worth it. The acting is about as lively as Ben Stein on NyQuil, the script contains more exposition than all three of the Star Wars prequels combined, and just about every character's name is pronounced horribly wrong from the word go. In all seriousness, the most rewarding thing about this movie was Princess Yue's gloriously phallic hairstyle, which you can probably find in about three seconds on Google Images, laugh to your heart's content, and then move on with your life without ever having to see the rest of M. Night Shyamalan's trainwreck of a film.
