I'm not really sure why this has so many negative reviews. I just watched it with 2/3 of my children yesterday (ages 6 and 8) and we all really enjoyed it. To start with, the animation was fantastic. The plot was interesting and kept everyone watching from start to finish. The "message" of the film was not, to me, heavy-handed or pushy, especially compared to Fern Gully, which came out around the same time. And yes, there was one part involving the death of two characters that was a bit "harsh", but this is certainly not the first animated film to do that and definitely not the last either.
