this Imax film was a disappointment to me.the back cover said the running time was 67 minutes,but the actual documentary is only about 37 minutes or so.the 67 minutes refers to the running time of the documentary and the making of feature combined.i didn't view the making of,just the movie itself.anyway,i felt the movie was not very ind depth and was too short.plus,i didn't really like the narration of Hal Holbrook.his voice just seemed to flat.there is nothing in the film that hasn't been done before,and better.also the film was not presented in widescreen,which was a big disappointment for me me.i will admit there was one great scene of a tornado,but it was short,and it was the only decent scene.a lacklustre effort,in my opinion.the DVD wasn't very expensive,but it still wasn't worth it.for me,Stormchasers is a 4/10
