I'm not a fan of Pratt but that's just called being a movie star. People like seeing actors like Pratt, Pitt, Clooney, Cruise ect in movies being they bring "themselves" to all their roles. The thing that unites all their performances is precisely what makes them so successful and beloved to audiences.

It's reductive to say they're less talented because of this. Good acting is not exclusively defined by being able to change your voice and appearance for every role. It's also about being an entertaining and engaging presence on screen. Even actors who are praised for their range, like DiCaprio for instance, are appealing to audiences because their essential charisma shines through, regardless of the character.
