The question of where this series needs to go (under water, space, etc), I am of the feeling that this series can only do one thing and it involves a mash up of two franchises:
Fast and the Furious and Jurassic World.
Hobbs shows up at Dom's house one morning, telling Dom that dinosaur's are running amok in Los Angeles. Hobbs needs Dom's team to help stop the dinosaurs. Dom, his team, along with Chris Pratt run around Los Angeles chasing dinosaurs. Again bringing the series back home, but also giving new life to these two franchises.
And they can simply call it-Fast and Furious: Jurassic World
