I would recommend this one first since it is the better of the two, and this is my opinion only. But, I would watch the other as well just to see the differences. Basicially, the plot is the same, but the storyline is different, (DOES THAT MAKE SENSE?? )
As for Dinosaur, I absolutely love that darn movie! I cannot believe the realism of the animation!! It's amazing what you can do with pc's today!
WOW, I can't believe your kids are that young, THAT'S THE BEST AGE (besides lack of sleep) Mine are 13 months apart, at least yours are a little further apart. 2 girls? or 1+1? unfortunately, I have 2 girls, LOVE THEM TO DEATH, but not looking foward to the teen or as they say now tween yrs!
I am tough too as far as movies go, but I've yet to see anyone not sniffle when I tell them to watch this one. ENJOY!!!

I got lucky 1+1, not that there's bad luck to having two of the same 'cause I won't care but the whole "older brother looking after his little sister" scenario is something I'm happy about.

I'm not complaining, I got the older sister looking after the younger, My older one is like a mother hen, even watching out for me! I could swear she is a 30 yr old trapped in an 8 yr old body! She's like my mother re-incarnated! That I love!

LOL That's great and I can actually see that scenario too
I know girls are VERY protective when there's two of them.
