Isn't this basically the same question as the Sword Oratoria reboot?

Regardless, DanMachi is never going to be more than 25 minutes or so per episode. Long episodes like that may have been a thing back then but it isn't now with midnight anime

It is a bit different as this relates to a re-telling of the main series but I see how they could be viewed as a the same.

One a side note, what do you mean by midnight anime? Are you just talking about channels that run certain shows late at night for the older crowd or is it something more specific?

Most anime you watch don't air during the day, they air at night past midnight, hence the name (or late night anime, whichever you prefer). Unless you're a shounen anime like One Piece you generally have your anime aired during the late night hours

Anime these days rarely get reboots, I can't think of one at all (Dai's Adventure might be one but I've never played/watched any DQ stuff)

You have a point. But if they do get a re-boot then it was because they had enough of a fanbase still interested in them to warrant a second attempt.

HunterxHunter (2011), Fullmetal Alchemist: Brotherhood, and Hellsing: Ultimate are a few that I can think of off the bat.

You could possibly include the latest Berserk anime but rather that would be considered a re-boot, a re-telling, or a sequel to the original is a bit hard to determine since I have not seen the original.

There were some good series which I wish that they would have continued. Kenichi: The Mightest Disciple was a favorite of mine and the anime series stopped with a lot of source material left to go. I would not mind if it got rebooted but I am not sure if it has the popularity to warrant a re-boot or a continuation.

D.grayman is a series which they started again after a long hiatus but it seemingly stopped being made again. Unfortunately, I think that was due to issues with the author and the source material.

Then there is one series that that I like which ionly aired for like 13 episodes and it is based on a novel series. I think it went by the name Dragonar Academy. The novels for it have not even been picked up by any company in the states for translation. I have to rely on fan translations to read it.

I know that Bleach is finally getting the rest of its source material adopted into an anime but I hope that they either change or expand upon the ending as the ending in the manga was a bit underwhelming for me.
