I agree with you re: concerns over Justice League trying to do too much, hence my cautious optimism. I'm a fan of Ms. Heard, which is where most of my optimism comes from. I also agree with you re: MoS and BvS: there's an arc at play that I'm really excited to see resolve--which isn't to say that's the only reason to enjoy MoS and BvS. I think their bad raps are MOSTLY because people didn't get what they want--that doesn't make them BAD. The rhetoric regarding BvS, in my opinion, was overblown.
We’re in sync here. I’m not saying that there haven’t been mistakes along the way, but it seems like the biggest sin MoS and BvS committed was NOT being MCU movies, not having the same light-hearted moments of humor or being too much ‘larger than life’ than their very human MCU counterparts… but the truth is, historically that’s always been the DC/Marvel dynamic - the Justice League have always been god-like icons, whereas by comparison, the Marvel superteams like the X-Men, the Avengers and the Guardians have always been the moody teenager looking to rebel or the old man struggling with his mortality and what legacy he might leave behind. They don’t have to be the same, they shouldn’t be the same.
I grew up a bigger fan of Marvel than DC, but a bigger fan of the current DCU properties than the current MCU properties (i.e. bigger fan of X-Men than the Justice League, but a bigger fan of the Justice League than the Avengers, Guardians or Defenders). I want the DCU to succeed and at the same time, I wish Marvel could regain all of their other properties so that we could see what could be done with them in their hands… an interesting analogy was made to me not long ago - the MCU’s first movies weren’t exactly the stuff of legend either. If you were to compare Iron-Man (excellent, but hugely successful due to RDJ’s resurgence), The Incredible Hulk (the largely forgotten black sheep of the MCU) and Iron-Man 2 (which received VERY mixed reviews) to Man of Steel, Suicide Squad and Batman vs. Superman you’ll realize that the two franchises aren’t that far off - its just that the DCU is suffering from comparisons to the MCU’s more advanced properties like Civil War at this point, not to mention a touch of superhero fatigue which I suspect will only grow in time.
The bottom line is that, to me, with the exception of the exceptional Logan, the DCU has been much, much closer to what the MCU has accomplished than pretty much anything else out there has been to it. The X-Men movies have been pretty universally bad in my opinion, the various reboots of Fantastic Four have been terrible and even as enjoyable as Deadpool was, its kind of an outlier that doesn’t really fit into the conversation anyway. Wonder Woman will go a long way towards determining whether the DCU’s stock is trending up or down, and I’m really hoping that Gal Gadot will prove as capable a leading woman as her supporting efforts seemed to suggest. I think she benefitted from particularly good writing and direction in BvS, really taking advantage of the mystique of the character and a ‘less is more’ approach, but in WW there won’t be any bigger names to hide behind
