From I understanding, reboots are often made to give an old franchise a fresh new look and start. To re- imagine the story under a more modern context or reinterpretation. Doing so is often done under the goal that said franchise is good and worth investing in but has died and won't be relatable to the modern audience.
With that said, what purpose did DmC have? Did we really need DMC to be rebooted? DMC is a rather influential franchise and Dante is a gaming icon. The franchise isn't all that old either. If it's because of the inconsistent storyline than they could just explain all that in another sequel. If it's to gain interest on the franchise, a sequel could do that too. The only explanation Capcom ever grave was that they wanted something different but did they need to go to another developer for that? They basically rebooted DMC with each sequel and gave us different experiences with each one.
What's worse is that while the reboot brought some unique things to the table, it was basically extending what we saw in past games (in terms of gameplay) and the story suffered from the same syndrome as the other games (just a little less severely).
So I wonder what was the point in the reboot.
I'm not sure either. The DMC storyline has always been inconsistent: each DMC's story stood on its own. I think people had made their peace with that since DMC2, and otherwise since DMC3. After all, it (sort of) retconned the story. In DMC3, Dante had always known Vergil, while in DMC1, Vergil had been lost (to Mundus) since Dante was eight. However, DMC1 never went into the story much, so Capcom can get away with that. I actually don't care that DMC3 slightly retconned it.
So the story inconsistencies are not the reason for the reboot.
DMC4's story was not tied to old DMCs, so again the story wasn't a problem; Nero was. He was intended to be Dante's replacement, but we still don't know how to explain his existence. We also don't know where his arm came from, and I doubt Capcom themselves know. It would not make much sense for him to be Vergil's son, but Capcom refuses to come up with another explanation. They haven't even officially stated he is Vergil's son. There are several ways to explain Nero. There might even be ways to explain his DB arm, but Capcom just doesn't want to put the effort in. Their staff lacks original thinking.
Capcom said they wanted to westernize the series. They couldn't do that on their own, so they hired Ninja Theory. However, it's possible the westernization thing was an excuse - after all, the DMCs sold
very well. I find it unlikely that after four games, they would suddenly want to westernize it.
They probably didn't know how to continue the story with Dante. They had planned to go on with Nero, but people didn't like him much, so they decided to 'save face' by rebooting. Of course, that begs the question: why not simply change Nero a bit? Make him grow as a character. Make him less whiny and more badass. Then people would actually like him enough. Again, Capcom didn't even try. Maybe they just wanted to take the easy way out - it could be as simple as that.
That still raises the question: why rehash old ideas? Why Vergil again? Why Mundus again, only now as the typical evil businessman? Hell, why Dante? Is their idea pool completely drained? And why such a throw-away story?
I suppose it's a way to start a single coherent storyline over the span of several games, but that's all.
The big question is: why alienate a huge part of the fanbase by changing so drastically the characters, dialog, art style, atmosphere, and the overall world? If it were a bit more faithful to the old series in the aforementioned terms, and had better controls, I might've liked it. But now, I have no interest in DmC whatsoever. In essence, they erased DMC and turned it into DmC, a game I feel 'meh' about.

Platinum is unrelated. I've seen you compare Metal Gear Rising to DMC before, but MGR was not meant to be like DMC, so the comparison to DMC is pointless. Its gameplay is not the same as DMC, and was never meant to be. I suppose its characters can be DMC-like, but that's no surprise, as the game was made by P* and the man who developed DMC1. His views on characters and his likes will shine through with every game he makes. The same happened with Gears of War and UT3. Anyway, almost everybody agreed it's a good game.
Bayonetta, I guess, is more like DMC. Back then, Bayonetta was as good as a very decent Devil May Cry game. Similar to DMC3 in quality, I'd say. You could do some amazing combos... unless you didn't know what you were doing. Simultaneously, it added a number of interesting gameplay features, such as Beast Form, fun minigames, and the ability to improve combos by throwing in finishing moves (QTEs). There were some things wrong with it, but I'm not going to go into that now. Still, it isn't a Devil May Cry game, so holding it to all the same standards is foolish.
I find it sad... for the fans. It's like Capcom wanted to try something new, but never bothered to ask the fans if they were up for it. They didn't want to take the effort to explain Nero, or to think of new ideas, and took the easy way out with NT. And yet, DmC is 'old hat' in some ways. And in other respects, it's not enjoyable to many DMC fans. It should've been more faithful to the old games in terms of story, characters, style and atmosphere, but should've improved gameplay more (minus the boring platforming). It should've been more daring. I still hope DMC5 will be made, to rival how good DMC3 was at the time. DmC2 and DMC5 alongside one another would be nice.
