I've probably said this before in a review somewhere, Warner Brothers have no clue with what they are doing since Marvel Studios released a movie called "Avengers". Quaking in their boots and doing the only thing Hollywood does when something is successful, and they want IN, or they think that they have a great idea, they force it. They copy and paste.
Warner Brothers (WB), would have done soo well if they followed Man of Steel with Wonder Woman and then The Flash or (from what they said at the time) the Flash and Cyborg movie and build their characters first. However, they decided on shortcuts and they rushed out a Batman v Superman (in which I had a much better storyline from my own head which would have spanned over 3 movies leading to Justice League). They rushed out Justice League which was, decent-ish. They released Suicide Squad which was, "Meh", ok at best I guess and now the only pretty decent films since, have been the Aquaman movie and a pretty good Shazam movie. In comparison to the line-up they gave many moons ago, what they have done fails miserably in comparison and that is not even comparing it to what Marvel has done. Not to sound like a Marvel purist, but this is one of the reasons why people look at the DC "universe" with disappointment because there is NO structure whatsoever.
NOW, we can only "look forward" to Wonder Woman 1984, Bird's of Prey (and the Fantabulous Emancipation of One Harley Quinn), The Suicide Squad (Suicide Squad 2) and Joker as it seems Warner Bros has thrown caution to the wind and seem to be getting their foot-in, solidifying who they are as a studio whilst simultaneously still confusing the audience and messing it up by announcing a new Batman movie called 'The Batman' yet rumour has it, the commissioner may be played by a black actor where in the Ben Affleck version, is played by a white actor, #sigh.
We can only hope that this Batman "year one" movie IS a prequel to Ben Affleck's and they bring back Henry Cavill for Superman at some point, he deserves it. As for this Joker movie with the actor not being Jared Leto and is a different Joker altogether, we can only hope this "elseworld" or "standalone" movie is good, well we hope.
