Yeah this was a big factor in my own falling out with anime.
Steins;gate is the first thing I think of here. I loved the first two thirds of it but then as it was starting to wrap up I'm like "this is lame."
............
This is genuinely a topic I find hard to add to, partly because I've talked about anime at length before and partly because most people have already said what I would say.
Bad endings, lack of subtlety....
And also there's just some quirks with the writing that bug me. It kind of goes into the "tropeyness" thing others have mentioned but....
I can't recall if I said this (I believe I did) but I use Saint Seiya as an example: the first arc has a villain named Ikki the Phoenix, who turned evil because of child abuse. But when Seiya finally confronts him and they have a chance to talk... it degrades into Seiya just screaming "but friendship is good, you have to have friends!" while Ikki says "I'll show you the power of a lone wolf!"
But... first of all that's retarded--Ikki had followers and thus probably did have friends on some level. He was not a "lone wolf." Secondly, nothing either of them discuss actually addresses the issue that the organization behind the Saints did some shitty things and got justified retribution for it. It's like it side-steps any actual discussion and instead just resorts to empty platitudes.
A lot of anime have this problem. This is where in some of my recent topics I get off preferring western animation like He-Man and the Masters of the Universe. When Teela and Evil-Lyn get a chance to talk in the episode "the Witch and the Warrior"... they actually discuss their differing POVs in a meaningful sense that relate to them. Teela doesn't just throw lame platitudes about goodness at her.
*Warning for an autistic rant from an anime fan”
Again, it all really depends on the anime you watch. I’ve seen just as many anime that managed to nail their ending and also manage to have meaningful discussions beyond just “power of friendship” platitudes. Mainly, the ones that are more seinen focused. Heck, even the slice-of-life shows tend to be better at this, as they aren’t concerned with life or death struggles.
I do agree that at times, it does result in typical platitudes being thrown at each other. That is why I tend to avoid long running shonen anime, as they are usually the most guilty about this. When an anime does try to do more than that though, and really delve deeper into a character beyond just simple “lone-wolf power” or “friendship will conquer all”, that’s when it leaves an impact. Heck, I wouldn’t be surprised if that’s why Evangelion became such a huge cultural touchstone.
On the note of endings, I’ve seen several fellow anime fans give a few explanations. Having to write not knowing whether or not the show will continue, leaving uncertainty as to how it should end, many shows being advertisements for a still ongoing manga, it being cut short, etc. That said, the shows that do manage to nail their endings do so very well.
I know it’s a rather weird thing for me to bring up, and I’m probably going on another autistic rant here, but it’s one reason why I like shows such as Madoka Magica. Stuff such as “the power of friendship” doesn’t work, and the main character only comes to her final decision after seeing everything else that happened, and chooses accordingly, and the ending is thusly satisfying, even when the sequel movie ends on a cliffhanger.
What was the problem you had with the ending of Steins Gate exactly? That’s considered by many to have ended in a satisfying manner. Not to mention it resolves character flaws in a way that doesn’t rely on platitudes as well, unless I’m misremembering.
And speaking frankly, I see a lot of the problems you mentioned in Western Animation as well, though again, there are definitely exceptions like Avatar TLA.
