If it's a good or enjoyable game or not depends on who you ask. The general consensus is that RE's quality gradually declined since RE4. It may very well have reached a point of quality that a large enough amount of people that Capcom surveyed were not ok with.

The scores don't show a terrible game, and some times scores don't really reflect what the overall audience feels anyway, as we know. Some highly rated games have been known to cause discord with fans, like MGSV.
But other than how others feel about it on paper, I can only attest to how I felt about it. And I thought it was a pretty bad game for the most part, and it had nothing to do with it not being a survival horror, because I was perfectly fine with that direction since RE4.

After how much fun me and my friend had with the co-op in RE5, we both found ourselves surprisingly unamused about this one. It was more like a chore getting through it, and we never played it together again since. I was planning to give it another go again thanks to New Game + infinite ammo fun, but they somehow managed to botch the infinite ammo mechanic as well. Which was related to the limited item storage system. I had to leave behind more items in this game than any other RE game because of the storage space and system. I wasn't running out of items as I frequently made use of melee attacks, as I normally would. It was just an annoyance.
The only portions of the game I thought were well made were the early portions of Leon's campaign, and certain portions of Sherry's. Which coincidentally (maybe?) also felt the closest to a RE game. In contrast to Chris' campaign that started off with a Call of Duty vibe.

After RE6 I no longer just assumed I'd have a fun enough with the game if the trailer looked interesting enough.
And in spite of FFXIII selling pretty well, Square said it "damaged the FF brand". FFXV also sold fairly well, but SE are aware of fans discontent with what they got and are constantly updating the game. We'll see what it ends up doing for the franchise in the long run, but needless to say when it comes to a franchise, sales numbers are important to reimburse the labor they put into that particular game, but for future entries in the series customer satisfaction rate is very important.
Final Fantasy VIII sold almost as much as FFVII, and more than FF IX, but I don't think that reflects user satisfaction rate, but rather blind trust in the series because of the popularity of FFVII. And I say that as someone who really liked FFVIII, but I'm not going to claim that it was objectively a good game because what's good to one person differs from another.
