I would never pay to watch an Indy film starred by Chris Pratt.

Because Chris Pratt is not such a good actor and lacks the qualities that the character needs (cynisim, vulnerability, maleness) and has already starred in many other franchises like Guardians of the Galaxy and Jurassic World. He is too beefy and also has a childish Disney Channel face that doesn´t resemble Indiana Jones, and would ruin the saga.
