It's interesting looking at these screencaps because I haven't seen that far in Tsuritama yet and I actually feel something almost "opposite" to your opinion based on what I've seen (only the first couple of episodes).
From the very first trailer the colours have "confused" me slightly in that the backgrounds are painted with what I think of as "character art" colours. It's like I'm expecting the whole thing to move at any given time, like in the excellent
OP to Welcome to the NHK.
I agree that everything is very bright, but it also creates a very homogenous style in a slightly negative sense - for my tastes there's not enough contrast, to be honest. It's like the whole show is one big, bright, perky thing - and although that's admirable, I'm not sure it's necessarily my cup of tea. That partly extends to the characters, although having not watched enough of the show I don't think I can assess those fairly.
I actually appreciate Tsuritama's visual style in this regard. Most anime has a divide between the characters and other "moving parts" and the background art, a divide which I occasionally find troublesome. It's as if two separate planes of existence are clashing together. So I appreciate that Tsuritama has everything looking like it exists on the same plane, in the same world; the characters aren't superimposed on top of paintings. The flat style that results from the bold color scheme is one I find rather attractive, and reminds me of Mononoke. In a more three-dimensional fashion, Wandering Son is another show I appreciate for making it look like the characters are a part of the same world as everything else.
Dead Bros in the Area
Fuck this show. I really do want to give it the benefit of the doubt... like maybe this is some Buddhist/Shinto allegory and that it's the Japanese equivalent of a shitty episode of Touched by an Angel or some other BS Christian allegory thing that's a dime a dozen on American TV, but holy christ.
The fact that the manga is an on-going concern leads me to believe that Japanese readers think this is perfectly normal and fine, so maybe this is like one of those Happy Science things and people just believe in dead brothers taking over people's bodies.
God, I hope the anime is done soon so I can put this to bed and pretend it was the Adachi-like show that it should have been. Or maybe I'll just pretend the show was about Seven playing women's soccer and that all the other stuff didn't exist.
It can be done whenever you say it is. If you hate it yet continue to watch it, there's clearly a problem!
As far as the concept of possession by a spirit goes, I don't think there's a problem with it in the abstract. I haven't seen it, but I recall that there's an earlier anime,
Le Chevalier D'Eon, set in 18th century France in which the titular character is at times possessed by the ghost of his dead sister as he investigates her killers. I think the big issue with how I've seen it presented in
Knight in the Area is the attempt to give the possession some pseudo-scientific explanation with the heart transplant, which makes it come off as nonsensical. Of course, there's also the general problem I noticed in the two episodes I watched that the entire execution - direction, art, animation, etc. - is too poor to take any kind of drama seriously.
Also, I don't think you're using the word "allegory" properly. Allegory is a simple means of symbolic narrative where A stands in for B; e.g. a river stands in for death. I'm not sure what A and B would be in your usage.
I guess DTL doesn't mind, because it's fucking insane to me that this is being treated as something serious. That characters in the show believe that the dead brother is playing through Kakeru at that point makes me rage so hard because no real, intelligent human being believes that angels, ghosts, dead bros, whatever, actually exist.
OK, putting aside
Knight in the Area, as a Christian I find this comment offensive. Are you really trying to imply that anyone who believes in the existence of the supernatural is an idiot? I really hope that's not what you mean.
