I Love Harry Potter

Do you think the harry potter movies should have kept the same tone as the first 2 movies? I think when harry potter 3 up to 7 came out they were trying too hard to be dark and edgy....i mean it is just a wizard school...and since it is it should look fun and feel fun...yeah voldemort returns but is that a reason for the whole school to look all dark greyish blue?? Its like theres no actual life when you look at the late movies.
