Liked it a lot, concur that it's not as good as the first, but a darker version with a Blade Runner type setting and feel.
I liked Farrell as Hauser--not nearly as good as Arnold but no camp involved so I think he was a worthy choice and did a good job.
Kate Beckinscale crushed Sharon Stone, though.
And I like Bryan Cranston (Breaking bad), but he wasn't a great Cohaagen.
Decent remake, a different movie from the original.
