What's the problem?
I don't really feel that this movie is any more or less mindless than your typical action movie. If you don't like mindless action movies, I'm kind of curious as to why you might watch this anyway, since I think the trailer openly presented it as such.
If you think this is the worst movie ever, I assume you haven't seen such masterpieces as Gummo, Moron Movies, and FearDotCom. Now THOSE are hideous pieces of crap.
Overall, Ballistic could have been better - but as it is, I found it to be an entertaining, visually appealing, mostly mindless action movie. And that was really all I wanted from it. I was relatively pleased with the movie. I thought it was by far better than The Transporter, which was an extreme disappointment considering the talent involved. And if you didn't like the music from Ballistic, then dear god, don't touch The Transporter soundtrack with a ten foot pole. I also thought this was far better than the mind-numbing "blockbuster" Vin Diesel vehicle, XXX. The motocross "action" in XXX really irritated the hell out of me.
I would much rather see a Ballistic 2 than XXX2... but guess which one's getting made?
It may be that my opinion is coloured by the amount of pure crap that I saw in '02, but I thought Ballistic was one of the better movies I saw last year. If you want to see a new movie that provides some entertainment that doesn't require much thought, this is for you. If you want something more meaningful, I personally recommend Road to Perdition and Equilibrium.
Why bash Ballistic when you could go bash FearDotCom, or even Wes Craven's THEY? Those two deserve it. =)
