I hate to be the bearer of bad news (potentially) but the rumors are that the movie follows this recipe almost exactly.
Tom Hardy has since tried to debunk the rumor but until we see it for ourselves, we won't know.
A lot of people thought there wasn't enough Joker in Suicide Squad and I thought it was way more than I expected to see him considering the source material.
Also as a stand alone movie - Constantine was/is still dope. However, considering I've since read Hellblazer and the new 52 run/Justice League Dark. I cannot accept anyone except Matt Ryan as THE Constantine now.
Onto the actual subject of the thread - Black Panther is definitely top 3. It's still too new to put it on top. I'd say Winter Soldier and Civil War then Black Panther followed by the first Avengers and first Guardians of the Galaxy to round out a top 5.
Still have hope for DC to turn their shared universe around. Maybe Flashpoint or Aquaman will save it.
Also for anyone who hasn't checked it out yet. Syfy's new show Krypton (kind of like a Superman/Man of Steel prequel) was pretty dope so far, and they did Brainiac justice.
(no idea if this is the right trailer because my internet is laggy rn)
