Of course Spinosaurus would've eaten other dinosaurs but not in the matter shown in that horrid documentary. Spinosaurus was primarily piscivourous and while I don't disagree that it would have occasionally killed and eaten smaller dinosaurs and crocodiles it wasn't always going out and searching for other dinosaurs to kill. Due to its specialized traits and niche the Spinosaurus grew so large because of little competition in it's niche. Another thing to add is that both Spinosaurus and Carcharodontosaurus would most likely rarely meet and compete against eachother due to their different feeding habits. An adult Carcharodontosaurus would be a major threat to a Spinosaurus and vice versa. Basically what I'm saying is that Spinosaurus would have been a generalist and it wouldn't actively hunt other large dinosaurs like Orunosaurus or large sauropods like Paralititan or Ayeptosaurus like Carcharodontosaurus.
