I'm not too worried about the story, because I feel like they will make more adjustments to the story of the camp origin story, but what does have me worried is the animaton. I think I remember Vincent Waller tweeting that the movie will be a mix of 2D animation and CG animation like SOOW, now it's said to be completley CG. The reason is this.
“Those have to reach a broad audience. I don’t think we can do 2d movies, to be honest. I think that’s hard.”
I understand, animation is very difficult, especially 2D animation, and a lot of time and work goes into it, 100%, but to me, this particular quote seems like an excuse to make the movie cheaper to make. 2D to me is very nice to look at. I hope this isn't true, but if it is, we should all accept that :(
But on the other hand, this is Cartoon Brew, so this could possibly be false :P
Anyways, I still have some hope for this movie, despite that it will be very different from the previous two :)
