The biggest disappointment was the lack of tension; one never felt that genuine peril was imminent. The spate of cartoonishly over-the-top CGI stunts and adventure scenes bordered on absurb, and ended up substituting for the lack of a fully-fleshed plotline. I wanted to like this movie, but by the time I'd checked my watch twice ("how much longer?"), I knew I was in trouble. The four adults gave a thumbs down, but the six kids (ages 10-16) liked it, so go figure.
