**Pros:**
**One Grew Over the Kuno's Nest** adapts a manga arc and fleshes it out to fit the short film title a bit better. I especially enjoyed the fact that it used more of the main cast. Seeing [spoiler]Ukyo, Ryoga and Shampoo[/spoiler] help out to take out a common enemy is something not seen often in the anime. The animation is just as stunning as in the other movies, which does help set it apart from the OVAs.

**Neutral:**
The reason why that difference is important is because One Grew Over the Kuno's Nest is a unique case. It is considered a short film but is the same length as an OVA. The only difference between this movie and an OVA is that it's in widescreen. Except the openings and endings are in 4:3 and only the movie itself is in the 16:9 resolution. This places it in a weird scenario where they went through the effort of animating the movie to the standard of quality a movie deserves but didn't end up finishing the job by making the whole thing widescreen. I'm unsure why they decided to go down this route, as the movie title sets people's expectations too high for what is mostly a regular OVA. If they wanted to make it closer to a movie and stand out more from the OVAs, they could've made it 10-15 minutes longer and made the movie's ending and opening widescreen as well. Speaking of the opening and ending, another change that could've been made is to make them match the movie itself.

**Cons:**
The opening Never-Ending Summer Vacation and ending Liar, are great songs on their own, but they don't match the movie in the slightest. You could swap them out with any of the other OVA openings and endings and nothing would change. Even though the other movies didn't have openings, they used that time to set up the film's settings more and their endings were used to create a nice bookend for the movie.

On the other hand, because of the disconnect between the movie and the opening, this movie's opening sets up false expectations, that when destroyed disappoint the viewer right off the bat. Considering the movie's short length, it could've used the opening to squeeze out more valuable runtime, instead of wasting it. The same goes for the ending to a lesser extent since the movie wrapped up fine enough, so there's not much else to resolve through an ending montage like the other two movies.
