I found this to be Better than I expected. Special affects are really top notch and hold up even after so many years since its release.
Its a fun film just watching all the disasters taking place throughout the film, mesmerizing even, although it can be a little repetitive. Acting was convincing enough and I guess that all you really need for a film like this.
It can be a little silly at times, but its all part of the entertainment. You are not supposed to take it too seriously.
It can also be a little corny, but I found it refreshing. For the past 10 years, its been nothing but humanities worst aspects reflected on the big screen, TV shows and news. Its nice to see a little hope from time to time.
