I have literally said the same thing.
Huntress is basically batman so an almost completely self created character and they made her a male created idiot.
Cassandra Cain might be my favourite new character and they should have called her Jane doe for all the relationship to the actual character.
Harley Quinn is brillant and saves suicide squad for me however the script just lets her down in this film.
Why can DC not work out what Marvel are doing and honour the source material instead of this rubbish we keep getting.
Because as DC's head said after the avengers movie was a hit, they're just there to cash in, they're not in it to make anything good.
And that's not disingenuous, of course they have to make money or they're not going to make the movies, but that's not the #1 goal. Marvel set up shop because they said people weren't doing their stuff right and they wanted to tell their stories right (i.e. their way) and if they do it right it opens up more and more possibilities. In their case, the more they make the more muscle they have to flex and try different things.
DC clearly isn't going their (Marvel's) way. DC's not running the show from what i can tell, WB is. The studio doesn't care if it's true to the source, or anything else as long as they get checks to cash. It goes way back, too. The Keaton/Burton Batman's did great financially and with fans (not all fans of course, nothing gets 100%), but the studio won the power play and dumped essentially both of them and went super neon and they went downhill all the way to bat nipples. They got it right years later with Nolan, and then went yet another way for this BvS era which was not popular and now they're going in yet another direction for a 4th iteration There closest Marvel comparison is Spiderman, but that's been sony's screw job, not Marvels. They had a good start with Toby and Raimi and the studio forced its way in and screwed that up, then they botched take 2 with Garfield, and they finally got it right - when they turned it over to Marvel, and now are trying to steal that creation back and will undoubtedly manage to screw that up in end. Sony, like WB, just wants a 'universe' so they can cash a check. I think they're the same group who wanted to bring back ghostbusters, but not just as a movie or a down the line, sequel, no....it had to be a 'universe' of which the original couldn't be a part of it for some reason then proceeded to start that off with the uber flop movie. In both cases, all those studios care about is a 'universe' they can build so that they can 'cash checks'. The universe and check cashing shouldn't have to be earned in their eyes, it should be bestowed upon them because they bought rights.
Say what you will, but Marvel wanted to build the 'universe' to tell their stories which do take place in a 'universe'. The difference is they knew that wasn't going to be bestowed upon them, they had to earn it by building it. They had plans, yes, but knew that if the first one didn't work, there'd be no 2, or 3, etc, so they had to make the best Iron Man movie they could make or the next one might never happen, and then if Cap didn't pan out, they may not have gotten to do thor, etc. All these other players seem to think they can announce a series of movies 'because it's a universe' and that if it doesn't work, its the public's fault, or piracy or something else, because they can't seem to grasp the fact that that stuff has to be earned.
