If true that most of the film is banal, that would be unfortunate. I was hoping for a sci-fi character piece as thoughtful as Time of Eve was, and I found the Beginning of the Day segments intriguing, though they didn't reveal what the bulk of the film would be concerned with.
I didn't see any of the promotional material for Patema, and I've still not seen Time of Eve (got the KS BD coming at some point, so I'm holding off on it until then), so I can't really make a content comparison. I think some of the other guys I was with thought a bit more positively about it than I did, but no-one particularly digged what they were doing with the antagonist.
-edit- Yeah, taking a quick scan through the Beginning of the Day segments, they look to be literally the first twenty or so minutes of the movie, which is by far it's best content. Not to say that there's nothing of worth in the rest of the movie, but that's definitely the best of it.
As a side note, it does feel like I see you say some form of "it was longer than it needed to be" about most films you watch.
I am not unaware of the fact that I seem to say this a lot about new anime movies. I'd raise the same complaint about Eva 3.0 and Yoyo and Nene, if I'm honest (well, in the case of Eva, it's more that 2.0 would have covered the same content better in half the time). I sometimes wonder if, by the time people manage to work themselves up to movie director level in the anime business these days, people are just afraid to tell them to more aggressively edit their scripts. I don't really mind things being contemplative (I love stuff like Honneamise and mid-career Oshii), but when things start reiterating themselves or dragging out scenes to the point of being heavy handed, I think it's a bit of a problem.
Strangely enough, though, I was totally OK with the running length of the Haruhi movie, and that was, what, almost three hours long? Conversely, the Index movie was probably too short, given it feels like they forget to include half the cuts from the movies climax.
