(A Movie Review -- SPOILER)
TFR and I rented and Watched I, Robot this weekend. I had avoided it because I had heard it plays pretty loose with Aasimov's original story, and assumed this meant it wasn't very good. I tend to be a purist when it comes to such matters (I'm still trying to forgive myself for enjoying LOtR), but I have never actually read the original novel, so I gave in and we watched it.
Altogether a pretty entertaining movie. It's morte of an action flick set in a sci fi background than a true SF movie. The issues raised by the Three Laws are actually, within the context of this movie, little more than a vehicle for delivering the car chases, gun battles, super-gee-wiz FX. The "villain" is supposedly taking over as a logical extension of the Three Laws, yet is blithely violating them in her willingness to eliminate those who stand in her way. And the ending was predictable, since the moment they introduced "VIKI" I knew they'd have to destroy her. There's a fine line between foreshadowing and telegraphic the plot.
All in all, it's a diverting movie and lots of fun to watch, but don't expect it to make you think as much as it tries to.
