Okay, so it seems that the Transformers movie did far better than hoped for, and with $300+ million a very real possibility in terms of box office performance, it should come as no surprise that Hollywood is looking for more giant robots.
To make this movie something more than an unneeded trip down Nostalgia Way, the characters need a change up. Pidge needs to be an all-out badass; Hunk should be the really smart one. Lamer in the Red Lion...if he is written as an emo-wannabe Hot Topic little bitch, I will do my best to end Hollywood. As for the leader guy in the Black Lion, make him gay.
That just leaves Princess Allura. They better not fucking change her. She was a princess who put her life on the line to defend her people when the original pilot of the Blur Lion was severely injured.. Also, she was hot. She could, however, use a little more depth to her character. Oh, alright! All the characters could use more depth, but Allura has always been the most interesting. She's not simply a tomboy character who is out to have fun and adventure, but a monarch-in-training who is committed to her people.
They can lose the mice, though. They were just lame.
