Still holds up 20 years later.. Even with the new 4k hdr these the graphics and action scenes area holding up to the test of time. It not only looks better than mainstream movies today, you're hard pressed to tell what was added in visual effects and what was happening at the time of the shoot.
The entire tower scene, not just the bottom level, is a thing of beauty. From all of the rain and explosions and bits flying around that you can see clearly now in 4K, to the generated explosion when the bomb hits the basement. Just gorgeous. Give it a watch, or a rewatch. It's worth it even now more than ever.
