"Doraemon: Nobita's New Dinosaur" is not only the 40th full-length film but also a commemorative film for the 50th anniversary of this national comic. Therefore, this film particularly brought back the duo "Kazuki Imai" and "Genki Kawamura", who previously served as the director and writer of "Doraemon: Nobita's Treasure Island".
What initially visually amazed me was the sense of presence in the dinosaurs' fierce battles. I don't know if this is the first time such realistic and vivid artistic scenes have appeared in a Doraemon feature film, but in comparison to the previous "Doraemon: Nobita's Dinosaur" (with two versions), the addition of 3D effects enhanced the shock and realism. Following Doraemon and his friends, it truly felt immersive, which I believe is one of the film's commendable strengths. 
Since this is also an original animation adapted from the original "Doraemon: Nobita's Dinosaur", the story contains many touching moments that move people, although these elements were already experienced in "Nobita's Dinosaur"... Oh no, perhaps exactly because I experienced them many years ago, that's why, as emotions are layered upon each other, I was unexpectedly hit with a super huge tear-jerker easter egg--"Pizu (Bizi)".
This also made me think that perhaps the reason the first half of Nobita's process of raising dinosaurs is almost indistinguishable from the previous work is to create a feeling of a "parallel world". It's like in DC comics, no matter which Earth it is, most of Bruce's parents will die. Therefore, when Bizi looks at Nobita and saves him, feelings and memories may constantly surge in his heart and mind. This could be the most romantic gift in this 50th-anniversary commemorative film for fans who grew up watching Doraemon. 
▼ If I'm not mistaken, this dinosaur model should be the T-Rex from the 1980 "Doraemon: Nobita's Dinosaur". 
But while indulging in emotions, there were also some significant drawbacks that quietly appeared with the plot. I have to say that this time in "Doraemon: Nobita's New Dinosaur", it can be said that there are completely no villain characters in the full-length film, at least excluding the enormous Pteranodon that attacks Doraemon and the others.
I originally thought that the film's main villain was the time patrol team, who usually contributes nothing. Moreover, the two team members were specially voiced by big stars "Takuya Kimura" and "Naomi Watanabe", yet they didn't have any significant feats or impressive performances; instead, they served only to watch and wrap things up like in the past, which left me feeling "What are you even here for?" This aspect is rather disappointing. 
Also, Nobita's astonishing arm strength really shocked me. It was at a level where it felt like in "Digimon Tri.", Suna was fine no matter how she was hit. Even though Nobita constantly showcases his inability to do pull-ups, contrasting with the smaller, slower-learning Q, later on, he can hold on to the Pteranodon for quite a while. That arm strength can almost be compared to that of the neighboring character who can effortlessly lift 999.9KG Pokémon, right? XD
The part about the friendship chocolate is also worth noting. I remember Doraemon mentioning that the effects of this tool replacing Momotaro's rice balls lasts only an hour, so one must use it cautiously. However, the time that Gian and Suneo were captured by the time patrol team obviously exceeded the tool's duration. Gian's dinosaur traits disappeared, yet the two dinosaurs fed did not show any aggressive behavior or create other surprises. Instead, the fact that the two dinosaurs eventually helped Gian and Suneo (and the drawing style didn’t change) was the most surprising to me. Was this hour really that long, or is it a bug overlooked by the writers and director? Regardless, it's a detail that's hard to ignore. 
Actually, because of these noticeable flaws and inconsistencies, even though overall this film remains an emotionally touching Doraemon feature, it slightly affects the emotional saturation, making it difficult not to notice these issues while being immersed in the story's atmosphere. This is really quite unfortunate. However, compared to the previous few original full-length films in the new series, this one still has many excellent qualities waiting for you to discover. After all, just the Bizi easter egg already made my mask wet with tears, I'm serious about that.
Moreover, the theme song "Birthday" sung by Mr. Children is really beautiful, and the timing of the music is also excellent. It easily lifts your emotions during touching scenes, adding points to this full-length film. In fact, the day the film premiered in Japan happened to be Nobita's birthday, and it also marked the 50th anniversary of Doraemon's birth. Plus, it echoes the birth of the new dinosaur, so it can be said to be a "triple celebration".
Another point that piqued my curiosity is that in the later part of the movie, there’s a scene that seems to hint Shizuka confessing to Nobita. I’m not sure if it’s intentionally connected to the upcoming 50th-anniversary commemorative film "STAND BY ME Doraemon 2". At least that moment really reminded me of the "wedding chapter" in the original comic. If that's truly what I guess, then I am really looking forward to how "STAND BY ME Doraemon 2" will perform.
