No, DaVinci was just bad. I don't expect realism, but I do expect interesting characters, engaging dialogue, fun action, and believable actors. This movie delivered on none of that. I don't begrudge the 7.50 I paid to get in, but it was nothing special, mostly bland and witless. I blame part of that on Ron Howard, who at best is just a mediocre director, and most of the blame on Dan Brown. He's just a sloppy, poor writer. It's a concept that could have been very engaging, unfortunately none of the creative people involved had anything of substance to bring to the table.
As far as my magic feeling in movies... I squelled like a happy little boy during Walking Tall when the Rock beat the snot out of generic thugs in a t###y bar. I nerded out when MJ called Pete tiger for the first time in Spider-man. And with King Kong, (not a great movie, but entertaining) I laughed and squeeled along with my buddies during all the island scenes. I still enjoy a good flick, but this just didn't do it for me.
As an aside, how can Steven and George make a movie about the cup of christ without pissing any Christians off, but Dan Brown writes a crappy little book and everyone gets upset? There were people outside my theatre protesting.
