SFV is a good fighting game. In order to become a great game it has to overcome a few hurdles and needs work put in to add content and network match stability among other features and fixes.
I didn't read a single argument posted here that justifies the amount of hate it received or in labeling it as a bad game.
Capcom didn't help themselves in the PR department and got some backlash it deserved however, the on-going extremity of hate received is simply a product of the internet generation, the mask of anonymity in social media and how harsh the FGC is on average. The game is alive and well, the community experience and popularity at tournaments such as EVO are a testament to that.
Elements that don't make a game necessarily a bad game:
Does not suit your taste
Missing features you want
Missing content you want
Missing the mechanics you want or are familiar with
Doesn't have great graphics
Doesn't have single player content
Doesn't have online multiplayer
You or others find it boring
Not your preference for art style
Missing an interface and system for social interaction and community within itself
Bugs, glitches or performance challenges are encountered sometimes when playing it
A game can still be considered good even if some of these areas are missing or need improvement. Look no further than the popularity of early access games or look at your own favorite games over the years growing up.
SFV has all the core foundations of being a good game in it's current state. Do I need to list them? If you are a fan of fighting games and have a history with them you will appreciate many aspects of SFV even if you don't like the game.
You don't have to enjoy it, or actively play it and can still be okay with saying "SFV's a good game but not for me since it's not my style or I feel it needs work or I'd like to see more content and features. I can see how others really enjoy it though.". This mentality also applies to other fighting games, none of which are bad games; Tekken, Pokken, MK, KI, BB, GG, Smash, Soul Calibur, MvC, Arms, KoF, Injustice etc. We are so lucky as FGC fans to be living in a time where fighting games are back on the path of increase.
The tragedy here is that if you're expecting some sort of mature opinion and attitude in this manner you're not going to find it in the FGC as a norm. In many cases that also extends to this thread and this board. The social noise is typically going to gravitate towards all or nothing thinking - a sour, entitled and immature demeanour.
