I had a free pass to see this before it came out, but either in conflicted with something else or I wasn't that interested in seeing it. In any case, I have now viewed it on DVD and it is a very good film. Just don't tell anyone it is really "Rear Window"!
I get annoyed with the dozens of remakes that are made every year and I always say that why don't filmmakers just take the same stories and create new characters and new situations with essentially the same plot, instead of just a straight remake. This is was happened here, and I think the film's better for it.
That's why "Risky Business" is as good as "The Cat in the Hat" (the book at least) and the recent "Martian Child" is as good as "Lilo and Stich" or "Clueless" is as good as "Emma" or "West Side Story" is as good as "Romeo and Juliet", etc., etc.
If you've seen "Rear Window" you know the basic plot, but instead of the voyeur being holed up due to a broken leg, he has a leg brace due to a conviction and cannot leave his home beyond 100 feet or so.
The suspected killer is near by and like "Rear Window", nobody believe the main character's paranoia. The main thing that sets this apart is that the story is updated to the 21st century to include the latest technology and attitudes. This is what really sets everything apart. The women in the film are sexy like in "Rear Window", but they're also strong and have no problem stabbing and kicking instead of just cowering in the corner while their man saves them.
