I'm not trying to convince you man. I just can't stand about 90% of the dialogue, I can't stand most of the characters, I didn't care about the villain at all. I could go on.
Once again, I don't care how popular this movie is.
Thats fine. Its cool to disagree. The dialogue was a problem for me as well. However, some of it is very comic booky, some of it sounds like dialogue from a the typical action flicks.
Like I said earlier. If you watch it after a Nolan or even a Snyder film....its jarring.
It seems your biggest issue would be you didn't care for the characters. I did. Thats what makes me buy what they're saying even if on paper its not that great. Most of the reaction has been positive towards the squad not necessarily towards the movie. So if you don't like the squad...then I can't argue/change your mind on that.
As far as the villain. I had no real problem with dirty witch version of Enchantress. The cleaned up version had very little screen time actually. They dropped the ball big time on Incubus simply based on the poor CGI.
However, the "villain" wasn't what the movie was really about. Marvel films constantly have villains you ultimately don't care about. Its just about how well you like the protagonists. Since you don't like them either...again can't help/change your view there.
I'd also say in hindsight David Ayer actually made a good SUICIDE SQUAD movie. I think a lot of people are getting lost in that fact. The trailers/hype sold it as being much more. The Joker included seemed like it would be soooo much more.
However, as a pure Suicide Squad comic adaptation to film it did the job. I totally see where Kevin Smith is coming from (especially after seeing the extended cut). The issue for some is Suicide Squad wasn't this widely popular comic. The Ostrander squad were actually overmatched villains fighting supernatural things like Enchantress/Incubus.
It makes me appreciate just how good James Gunn did to make Guardians of the Galaxy as good/universal as he made it. However, as a Squad film Ayer did the job.
Its just too bad there was some meddling going to make it more accessible to the general audience. It took away from it.
