I would like to see those scenes for sure, but am I the only one who thinks having them re-added (if that's ever going to happen) would hurt the film instead?
I'm somewhere in the middle. There are some things that were cut which I think would've made the film better, like the full version of the Sharptooth chase near the beginning. But then there's certain things I prefer in the final version, such as with the discovery of the Great Valley and Littlefoot seeing his mother in the clouds. To me it just feels more complete and emotionally-satisfying to have that part at the very end.
That, and if Littlefoot had discovered the Great Valley earlier on just after his fight with Cera, then it doesn't make sense to me that, after the trip through the volcano area, that he would let Cera wander off on her own after the tar prank and ultimately leave the group. Like, if Littlefoot already knew where the Great Valley was, then he
knows that Cera won't find it after she storms off. Obviously she was mad and needed time to herself, but I think eventually he would've gone after her to try and convince her to come with them. But in both the script and the film proper, it seems like she'd left the group seemingly for good, and they just let her go, which I don't think would've happened unless they
hadn't found the Great Valley yet.
Regardless, I would still be immensely grateful if the deleted scenes ever turn up someday, and I'm sad to think that the footage may be lost forever. But I am happy that we have the script, at least, which is the next best thing.
