Lost in Our World. Found in Another.
John Carter (2012) is a sci-fi movie about John Carter and his interplanetary adventure based on Edgar Rice Burroughs' Barsoom series of novels.
Synopsis: War-weary and former military captain John Carter (Taylor Kitsch) is inexplicably transported to the mysterious and exotic planet of Barsoom (Mars). He is reluctantly embroiled in a conflict amongst the inhabitants of the planet, including Green Martian Tharks led by Tars Tarkas (Willem Dafoe), Red Martian Zodanga led by Sab Than (Dominic West), Red Martian Helium's captivating Princess Dejah Thoris (Lynn Collins), and White Martian Thern led by Matai Shang (Mark Strong). In a world on the brink of collapse, Carter rediscovers his humanity when he realizes that the survival of Barsoom and its people rests in his hands.
I think I'm watching a Star Wars-like movie with some elements from Avatar and a bit of Airbender. But then again, the novels were written in 1912-1943 and that was almost 100 years ago. So, I guess it's fairer to say successful movies such as Star Wars and Avatar are inspired by these novels. Unfortunately, since John Carter comes out later, we tend to assume it "borrows" elements from Star Wars and Avatar.
The storyline can be a bit confusing and overwhelming for people like us who haven't read any of the novels. However, if you like fantasy sci-fi movies, this movie would really give you the sense of enjoyment and entertainment that you like. Putting aside forced chemistry between Taylor Kitsch and Lynn Collins, you might find the rest of the story engaging and entertaining. The visual effects are pretty impressive too.
Go watch if you haven't done so!
