Story [7.0]
The story is a bit of a disappointment. Of course, this is just short of 30 minutes, so everything has to wrap up in that time. However, I felt that it could have been extended longer, mostly in the flower-caused mischief. It could have started to be small things and escalate to much serious things, but it wasn't meant to be. The best was arguably the moments that Doremi and Pop spent together and things are revealed about the main character of the series. However, before you know it, you're at the end, which is rather predictable but still has a few hidden things that may require a second look. In short, okay story but had the potential to become extended and deeper.
Art [8.75]
The art is pretty much the same that you would see on the TV series, except for a smoother frame rate that are typical of animated feature films. However, these moments are not constant, but it was a treat to see them when they appeared. [UPDATE] Apparently, my computer has fixed the video to its original widescreen format, so I bumped up the score just for that.
Sound [7.0]
Copy + paste from the show, but the ending song had a Latin vibe (like the OP), so I enjoyed it.
Character [6.5]
The focus on the movie was on the two sisters, so they were pretty much the characters. Everyone else is just...the same from the show. It was very nice to see the oft-quarreling siblings have a nice talk (and revealing interesting secrets) and looking out for each other...but how long will it last?
Enjoyment [6.5]
If you watch the series, you'll like it, but probably not more than the show. If not, you're going to pass it.
Overall [7.0]
An okay attempt but it feels like it should have had more involvement in the story and characters. Too short and maybe too focused, but there were a few character backstories that make it interesting.
