I'm a big DC fan. My favorite television show of all-time is Batman: The Animated Series (live-action goes to Daredevil). Among my favorite films of all-time at Batman films. I absolutely adore Justice League and Justice League Unlimited. I've read more DC comics than I care to admit...
...and I've mostly disliked to at best been unimpressed with modern DC films. I didn't hate Man of Steel, I really didn't. In fact, there's some stuff in there I REALLY liked (other stuff was meh for me) and I do think Cavill is an excellent Superman. I also thought the score was gorgeous! I rather liked Wonder Woman a lot, though I do think the climax devolved into a video game. I think the other I enjoyed most was probably Shazam, it was nice to see a lighter modern DC film. I did enjoy Joker and The Batman, though I have my nitpicks, but thought they were pretty darn good mostly...but they don't count really as they're not part of the DCCU. I thought The Suicide Squad was...dumb enjoyable fun. I enjoyed it, but I wouldn't say it's got much lasting power for me. But for me, Aquaman, WW1984, JL, Birds of Prey, BvS, and Suicide Squad, were anywhere between "meh" to downright awful. All of them had elements I enjoyed in them though, more or less.
And I must admit, I thought the Peacemaker series was GREAT!
But I do think it'll be nice to get new heads of, because I think DC has potential. Hell, I know it does. I mean look at the Timm animated universe. They're among the greatest shows ever made. I could talk about BTAS and JLA/JLU all day. Those STUCK with me on a very profound level. These characters have the potential to give us stuff not only as good as the MCU Phase 1-3, but potentially better...they just need the right creative team. Snyder was NOT that. I hope this is the right one.
