Ebert: Don't Watch the New Harry Potter Flick in 3D  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 color.  As a devout
follower of the Cult of Ebert, I'll heed the man's word.
