Went and saw it last night. If you've seen the trailers in theaters and/or on TV, then you've already seen about 80% of the weather special effects. In fact, I think I had already seen the entire frickin' tornado outbreak before setting foot into the theater. There also was some pretty shoddy editing...in the scene where Dennis Quaid's character briefs the president about evacuating the southern part of the country, he draws a line from coast to coast, with the line running just south of Ohio (threw the middle of Kentucky or close to the Tennessee border). A few seconds later when the shot returns to Quaid, the line now runs through the southern half of Ohio (between C-Bus and Cincy), and when the shot returns to him a third time, the line is back below Ohio but a little higher the the first one. However, there still were some good effects (the computer generated images of the earth from orbit were killer) and all-in-all it was a decent movie, if you're into escapism.
