A good watch, particularly if you've never seen if before.
Picture quality however isn't exactly Blu-ray reference material, but the high def transfer is significant enough that it clearly exposes many of the tornado scenes for the CGI that they are.
Nevertheless, tackling tornadoes with mid-90's special effects was very ambitious and is still well appreciated when watching the film – Just don't expect to be wowed to the same degree as other CGI-heavy movies.
