I think Universal is afraid to use practical effects after Jaws, Earthquake/Disaster, and Twister all had high costs, and a low reliability. As someone said before, Disaster was probably on it's last run, and Twister was not far behind. That being said I'd love to see this use practical effects, i mean practical effects just have a more exciting feel. Back in the day when the truck fell down and exploded, it was so crazy! And then when the other train derails, it was spectacular. I just wish Universal would experiment mixing more practical effects with their screen usage.
