I finally watched the movie.
How I felt about it is complicated. It's not really about Doremi, it's about a bunch of dreary real life stuff instead. Drunk old women and their love lives and careers. I wonder if the movie would have been better off inventing a show-within-a-show in place of the Doremi series. And if it's supposed to be this realistic story set in the real world, why do the three women talk about Doremi so much and take stuff from the show so seriously, adults don't do that. I didn't understand the plot point with the guy who liked Onpu, why does he post that stuff on his facebook, why is it supposed to be a big deal that he does it or that there's (completely offscreen) negative posts from others about it, why were he and Sora so neurotic about the possibility of being a couple, just give it a shot and stop worrying about all this stuff that doesn't matter.
To the movie's credit: if it can affect me emotionally like this, it's doing something right. I watched Doremi not even three years ago and all this stuff is capable of making me feel nostalgic, sometimes even nostalgic for a past I didn't even have. I liked Reika, genki baka types are a bit of a gimme for me. Each woman's favourite character was different to the Ojamajo she acted most like. Sora's favourite is Doremi but she was like Hazuki when it comes to expressing her feelings. Mire's favourite is Hazuki but she's most like Aiko with how she bluntly says stuff and how she has a bit of an accent. Reika's favourite is Aiko but she's dopey and falls in love easily like Doremi. She missed out on eating the steak too. I was happy for the women in the end since they managed to get started on their dreams. It was elegant how each character's ambitions were furthered by the same thing, the Maho-dou Cafe, in some way.
