I was going to get this on Blu-ray until...
... until they ruined the movie with the entire family forsaking/betraying Grug (husband/father)by choosing to go with Guy (the newcomer). Hollywood [repeatedly] acting out behaviour like this sends a bad message & sets bad examples to kids. In case any naysayers are going to try & argue that it's just entertainment, or that good parents should be the example setters, you're 1/2 right. Children with strong upbringings & high self-esteem, who are reared with sound values would be least influenced... BUT what about all the other youth, who watch far too much TV & don't have the best parents?
In short, the trash they put out today is NOT a positive influence on the youth of today. I mean, c`mon, how many shows/movies these days have little kids telling their parents "I hate you!"
If you disagree with the foregoing, then you're probably one of the kids who had parents who didn't care enough to discern the difference between suitable viewing material themselves... & probably have kids who've said "I hate you...." or will one day!
