I watched some Arrow, and while I didn't find it terrible (outside of the usual WB cheesiness, and the wonder of how no one recognized him when he wasn't wearing a mask) the one sticking problem I had that didn't sit well with me is that Ollie kills -a lot- of people in that show.
That actually becomes a major plot point in the second season. It's what people have been hoping will happen with Superman in regards to him killing Zod in MoS, but I feel like it was done much more naturally in Arrow because they had time to build his motivations for what he does and his eventual turn away from killing makes sense form a character development standpoint.
As for the new movies, I have no doubt that they will make money hand over fist. Even Green Lantern grossed over 100m dollars, as did the FF movies, Ang Lee's Hulk, and any number of horrible superhero movies, so the money as a metric for success is hardly good.
Here's the thing though. I, in general, seem to have a much lower bar for bullshittery when it comes to comic adaptations. I was able to enjoy the FF and Daredevil movies. I know they weren't great, or even fully faithful adaptations, and they had questionable acting, but they were kind of stepping stones towards what we have now. Kind of like the comic to movie screen puberty period. Gangly and awkward and not quite fully formed.
Also, I do have to repeat, when I'm talking about DC losing its way, I'm not just talking about the movies, I'm talking overall. The comics are shit in general, thanks to the editorial mandate to make everyone dark and gritty (i.e. Batman). I think even the animated universe is starting to lose some of its former glory now that Timm isn't as involved in them and they are doing their own New 52 universe now.
I do have to say that the two things that they are doing right at the moment are Arrow and The Flash. Particularly The Flash, because they're bucking the trend of trying to make everything all gritty and realistic. I loved the Firestorm storyline and they managed to keep it relatively faithful to the comics.[DOUBLEPOST=1425660239,1425660115][/DOUBLEPOST]
I thought Injustice was a raging piece of crap, for the same reason I hate Man of Steel. Green Arrow has always been a second rate Batman clone, so when you apply a darker tone to the character it works for the same reason it does with the Caped Crusader. Arrow excels at providing that mood, while still maintaining the character traits that keep Oliver Queen unique. Note the producers did not just copy their formula for Arrow over to Flash. They looked at how Flash works as a character and tailored the show to match the character, taking an approach more like you would expect to see with a Superman franchise.
I don't agree about Injustice. The thing about Injustice is that it's essentially an elseworlds story. Of course the heroes in the alternate dimension are dark. THEY'RE the VILLIANS. The real Superman was horrified by what the alternate Superman did.
Also, Arrow now has The Atom flying around in an Iron Man type suit, so it's also embracing the "comicbookiness" along with the more dour portions of the show.
