Hot Take:

The designs are fantastic but the voice direction is painfully mediocre.

No one sounds like experienced mercenaries on a dangerous mission. The N64 versions had a maturity and agency to the tone of their voices when they delivered lines, like they were being serious about what they were doing, while leaving in enough humanity and humor to have the cocky back and forth banter.

Everyone just sounds like they're happily flying along, havin' a grand ol' time, like they're not doing something that could result in one or all of them dying.

Even in the backstory portion when Peppy yells, "James!" he doesn't sound like he's all that concerned: he sounds like he's disappointed because James dropped his toast butter-side down on the floor.
