I, Frankenstein is big on effects, especially in its IMAX incarnation, unfortunately, the story didn't carry the promise it made in the interesting conceptual ideas. The dialogs are flat and uninteresting with a few long winded and boring explanations. The characters lack any depth and some of the actors are not even good, although that might just be because of the terribly written parts they have to play.
Just for the special effects.
