Left after 45 minutes. Seemed it was trying to be an action movie and special effects movie and sci fi as well. No character development to speak of and plot didn't take shape. Wanted to like it, but couldn't see wasting an additional 2 hours hoping it might.
Didn't flow smoothly..... unprompted behavior made me skeptical. More time was needed to develop some of the story line to get audience buy-in. Felt disjointed.
