I think saying they are out of touch with “the fans” is a bit of an over generalization. As others have pointed out they clearly want to be another MCU (even though literally no one has been able to duplicate that shared universe formula but in theory DC would have the best shot). But it wasn’t comic fans who made them what they are today, it was mainstream fans. MCU appealed to a wide range and most of which had little to no interest in the comics themselves. MCU actually varies quite a bit from the source material, even if they do draw from it. But they found a formula that worked and made consistently popular movies so they made it work.
But to me saying DC Movies have been a series of failures is really selling them short in a lot of ways. They managed to bring back Batman with the Christopher Nolan films and make them a hit even before the MCU. The DCEU movies have not been consistently well reviewd. But in terms of making money, which is what Warner and later ATT wanted them to do they have mostly succeeded.
Man of Steel, Batman v Superman and Suicide Squad all made a ton of money at the box office, part of why they never course corrected despite the less than stellar reviews those DCEU movies got. Wonder Woman was a big success both comercially and with critics and fan reviews. Their first real failure was Justice League. And that definitely was and while it is easy to blame Joss Wheedon now and criticize them for not sticking with Snyder given what has gone on the last few years especially. A lot of the people I knew who didn’t see that movie didn’t because they didn’t like the last ones and thought WOnder Woman was a fluke, so they got tired of being dissapointed. On paper bringing in a guy who did the MCU team movie success was not a bad idea even if it didn’t work out. The decision has not aged well but I think most forgot that up until that point many if not most wanted Snyder off the DCEU. Again no denying it didn’t work out, and bringing in Joss clearly didn’t save it. But on paper it was not a bad idea at the time, the decision has just not aged well.
But after that they went on to have success with Aquaman who did MCU level numbers, then Joker also both got huge numbers with on a relatively small budget and was nominated for Academy Awards. They also did well with Shazam! which was no billion dollar movie, but made a profit and got a sequel green lit. So clearlt Warner/ATT were happy with it.
Birds of Prey was a failute although it did just before leaving theaters make a small profit. Small was not good enough for what they needed, and while some blame Covid and obviously if it has stayed in theaters longer it would have made more pretty save bet would not have been a huge money maker even then since Covid hit near the end of it’s run.
Wonder Woman 84 is harder to guage. It did underperform in the box office but Warner was pretty quick to announce a sequel, so clearly they were happy with what it did for MAX.
And of course the animated direct to DVD films have been mostly successful, way better than Marvel had done with their attempts to replicate that idea. And while Disney+ will likely give them real competition now that those series are up and running, The Arrowverse and the DC Universe originals that are now HBO MAX originals have been consistently good and gotten mostly positive reviews.
So I don’t know they are out of thouch. They have had a lot more hit’s than missed and the only true failure across the board was Justice Leage and you definitely messed up when you can’t even break even on a movie starring some of the most recognisable characters in the world. But even so one movie with critical and commercial failure, and one movie that barely broke even and got mixed reviews is not a bad track record.
And you could argue that it was listening to the fans at least in part that has them potentially about to correct the mistake they made with Justice League.
It only looks bad next to the MCU which yeah maybe not good THEY are the ones showing DC up from that standpoint. But I would argue MCU has set the bar so high few will meet it any time soon. They paitently launchd a long term plan that likely even they didn’t realize would become what it was.
