As for the plot, it is fairly well put together. The story has for the most part, a constantly escalating feeling, but I wouldn't say that it is super suspenseful. There is pretty much no love story, which is also refreshing. There is some action... but it is with cats, so that becomes more humorous than intense. The movie also has a decent moral too... which doesn't matter much... but hey.. its there!
The art is also a step above most of what I have seen from Studio Ghibli, the motions are fluid and the scenery is vibrant. the colors in this one are also very vivid compared to a few movies I have watched. The expressions like all of Ghibli films are awesome, even on cats.
Anyone else with me here?
