Not much to see here. I came as an enthusiast of space-themed anime, but this wasn't about space at all, but about physics, mathematics and calculation. The story is shallow and nothing interesting happens at all; you are left with a couple of beautiful, very well-animated scenes, but no compelling events for the plot. They study, they drink, they build a kind of spaceship, go on their mission and... That's it. It's like you're seeing a slideshow of some trip your uncle Joe went to in 1979 and all he talks about is how good it was, but you get no feeling out of it, you justcan't relate. Uncle Joe is a bad storyteller. Maybe he worked on Spirit of Wonder.
The animation is adorable, the designs, the colors, the faces of the characters, all make you smile. Good music, it gets the mood right.
You don't get to know the characters very well. This is why I'm saying it's pretty difficult to care about something here. All you see them talking about is science. Ok, the title is SCIENTIFIC Boys Club. But at least I was expecting some kind of uh deep human relationships. I see they laugh, argue and smile, loving science together, but I don't see why. I can't understand how. Windy is the only likeable character there, yet she almost never talk.
If you're not expecting a compelling story and just wants to kill time, this can be a good, beautiful surprise. For me, personally, it didn't work.
