I like the new graveyard, although I think it should be a little bit bigger, and I agree it needs to be darker, i.e. more shady. It would be more atmospheric, and also less brutal during the summer months.
I don't really get the idea that they are too funny. If you read the original gravestones, they are just as witty and funny as the new ones. I think that the ride just didn't have gravestones like the new ones when it opened because the technology didn't exist.
Still, I kinda wish it was a bit bigger and more spaced out, giving the crypts the room they need and allowing more guests in from the main queue. Although, maybe Master Gracey's crypt is too small because they don't want you thinking someone's buried there. Don't want uptight parents freaking out.
