While I think it will be a Ok movie, and while I love Tom Holland, I don't think it's his vehicle. Maybe he is too young or hasn't had enough time away from MARVEL. When I see this, with his tone of voice, it almost sounds like Peter Parker.
I am not expecting him to crack jokes and have timing like Nolan North, but he still sounds like "insecure/anxious Peter Parker", because I think he looks great with the action scenes but then when the pacing slows down for plot, he just still sounds like Spiderman.
