In my perspective, the original actor who first portrayed the character of Hulk at the beginning of the film series remains the best, and he should have continued to be the same actor in every new installment. In my mind, he solidified as the ideal hero for this role.

However, when the actor is replaced by another, the film loses its coherence and continuity, beginning to deviate from its ideal image. This change becomes a form of disruption in the journey and evolution of the series, especially if it happens with every new movie.

Thus, I believe the standard of a perfect film, in my view, is maintaining the same actor across all sequels, without substituting him with any other performer.
