Even if it won't last, best case scenario, you're looking at *several* upcoming remakes. That's a plan for many years ahead. And experimentation not being reserved for indiesphere feels good.
Where are you getting the figure of "several?" There's the RE4 remake, and that's it.
Who's "we"? I never really complained about RE storylines going batshit.
"We," as in, the fanbase in general.
To be clear, this isn't about storylines, but more the drastic shift of tone and setting that occurred post-RE5. Said it before, I'll say it again, however you feel about the plot, you can more or less draw a line from RE1 to RE5, and consider it all part of the one story. RE5, among other things, wrapped up Albert Wesker, gave us the origins of Progenitor, and a lot of the game's plot is in the shadow of Umbrella, even if Umbrella itself is gone by the game's timeframe. Also, almost everything up to that point was in the same tone - zombies, light sci-fi mixed with horror, etc. As in, the likes of the T and G-viruses were clearly explained as to how they functioned.
After 5 though, what happens? Well, we get RE6, which I haven't played, but basically throws in Neo-Umbrella and The Family - in other words, The Illuminati. That doesn't work, so we get Revelations 2 - horror more in the style of Saw (though according to Brawlman, based on Evil Within). Whatever it's based on Revelations 2 is a different style of horror from previous games. Then we get RE7, which is almost completely isolated from the series plotwise, and is 'chainsaw horror' or 'hillbilly horror,' with a touch of the supernatural (yes, Eveline's abilities are explained, but they're supernatural from a writing standpoint). RE8, we're doing vampire horror. This in the midst of remakes of RE2/3, which are nice, sure, but the differences between them and the recent entries are like night and day in terms of context.
So in other words, focusing on the main series, up to RE5, we get a series that's fairly consistent - up to RE5, I say "Resident Evil," you'd probably have a good idea as to what it is. But now, as of RE6, and for four straight entries (RE6, Revelations 2, RE7, RE8), we have four entries that are drastically different in tone, setting, and plot, with said plots existing in isolation from one another, with the exception of RE7-8, maybe. Whether this is a good, bad, or neutral thing is up to you, I can't speak for anyone but myself. However, I do personally find the lack of acknowledgement in this shift for two reasons. One, a portion of the fanbase decried RE4 for pivoting more towards action (I'd argue the pivot was made in RE3, but whatever), and while I can understand that, RE7 felt more like a departure than RE4 did (to me), yet people heralded it as a 'back to basics' kind of game (it isn't, IMO - the Baker Estate may have elements of the Spencer Mansion, that doesn't make it 'back to basics'). Two, I can name numerous other series that have had 'identity crises,' and most of the time, people have been iffy about the shift in 'identity.' Resident Evil, for whatever reason, appears to have escaped this debate.
