Roger Ebert dropped his review on the final Harry Potter movie, and guess what? He likes it! But there is one thing he doesn't really like: the 3D.
An original detractor of the technology, Ebert doesn't say that it ruins the film, he just found it completely unnecessary.
Note: This entire movie is dark, gloomy and filled with shadows. So it should be. That makes it particularly inappropriate for the additional dimness of 3-D. There are a few shots that benefit from 3-D (I like the unfolding of the little magical globe) but none that require it. Avoid the surcharge and see the film in proper 2-D with brighter colour.
As a devout follower of the Cult of Ebert, I'll heed the man's word. [Chicago Sun Times]
