Overall I really enjoyed the movie.
I thought it was shot really well and the action was kept up throughout. I also enjoyed that the movie seemed to know what it was talking about (for the most part). I was pleasantly surprised by a summer blockbuster movie which isn't common. I also really enjoyed the cast, I thought that the chemistry between them was believable and reflected real world storm chasers well.
The story was alright, nothing too special. It did seem like some aspects of the plot were pulled straight out of the original Twister movie and at times pulled me out of the immersion when I recognized this.
Overall I'd say go see if I'd you want to, I will probably go again.
