But imagine if they made the Rick Riordan books into a movie franchise like the Marvel Cinematic Universe that followed the storyline, casted actors that were the right age and the right personality and everything, with end credit scenes hinting at the different mythological worlds and big crossovers and Rick Riordan cameos

No they should have made Percy Jackson into a series instead of a movie franchise. It would have allowed for more coverage.
