I don't remember a movie whose visual effects are of this scale, and only those of King Kong are superior. The early scenes are much fun, with nice superficial touches reminiscent of Transformers. The whole thing is dragged by some family drama as well as an uninteresting John Cusack. Me loves the designs of the arks. The 'chase' scenes, all an excuse to showcase the extravaganza that is the effects, are pure fun. I also enjoyed the large Russian billionaire, an otherwise unconvincing buffoon that offers much comic relief.
