Imo, I liked a lot more the songs in this version and there are some parts that are more... "doraemon-like" (better). Instead of forcing Judo to follow, they talk him over just like with lilulu in both. The other movie explained other things way better and many interactions between characters specially Lilulu + Shizuka and Lilulu + Nobita were better and less rushed.
I wish that they had used the best of both ideas to make a better movie than the "original" but they ended up making one just "as good".
Final note: I didn't like dorami here. It was really wrong and a very low move from who forced that to happen!
