But they make no effort to sound like kids. It sounds like Kevin Hart came into the recording studio with some coffee, recorded his lines and left onto the next thing he had to do that day. Yes, I'm sure actors do this, but it doesn't sound like much effort was put in. It looks more like, "We got Kevin Hart and that's enough! Bye Kevin!"
This trailer looks like a generic animated film ripped the face off that was these books and is now wearing it for a face, parading around to give the appearance that it's a Captain Underpants movie.
