Did anyone else notice..
That the transfer for the DVD is bad enough to actually hamper several of the effects shots. In the trailer, you can clearly see the Warlock fading away as he escapes, while the dvd version is so dark you just see him on the screen and just assume it is a reaction shot. The storm also looks much clearer in the trailer. Just another reason for this to be re released on DVD.
***EDIT****
The new version playing on HD Net is fantastic and reveals new detail not seen before.
