The movie was stupid, retarded fun. It was not a good movie, but I'm glad I went. In fact, I would say that I'm the opposite of most reviews I've read: the first part was scatterbrained with no sort of organization at all, but it came together later and made a movie. The bit with Boomerang telling Slipknot the bombs are a lie to get him to rabbit and test the explosive in their necks was straight out of issue 9 of the Ostrander series. So I actually expected that and was amused when they actually did it.
That said, there wasn't nearly enough Digger dickheadedness in this movie, though. Boomerang was a massive douche lord in the old book, and it was fabulous. Rick Flagg was a puss. Totally didn't like how he was setup. In the comics he was basically GI Joe: a "he never gives up, he'll stay 'till the fights won" type of character. Now he's a love-struck soldier boy who seems in over his head all the time. Enchantress was an intriguing route to take for a villain: she always had the potential in the comics but never really was let loose. I just hated how she looked, as the comic version would have been hot on-screen. Instead she looked like one of Swamp Thing's moss-covered vegetarian ass nuggets.
I was disappointed that Smith's Deadshot had none of the fatalistic and suicidalist outlook of the comic versions...then again, it's Will Smith starring as Will Smith: dude's like Black John Wayne. I got the feeling that El Diablo would bite it early on since he was more or less repentant and probably wanted to die, but he was too much of an unknown that changing into a fire demon was just a deus ex machina twist. Harley was well-done, and I like how the Joker was used here despite that it wasn't enough. I still don't like his look, but Leto's Joker isn't bad at all. Looking forward to the two of them in the Batfleck movie, particularly when it was shown in the movie that Harley was an accessory to the murder of Robin whose outfit we saw in the Batcave with Joker spraypaint on it during BvS.
So, yes, I actually broke down and watched Batman v Superman: Dawn of Justice Ultimate Warrior Director's Original Vision Version before going. And while that movie was crap based on the fact hat both B & S were idiots throughout dancing on a string for a hipster apparently Darkseid quisling Luthor, they do link together rather interestingly and form a basis for more films that hopefully will suck less due to increase focus and learning from past mistakes (yeah, right). SS shared the issue of BvS that they tried to shoehorn in some stuff and characters that they could have done without, but while the latter was a slog all the way through the former had some fun bits I could appreciate all the way through.
As for the Waller rescue, yeah, it was lame, but in context it made sense that Enchantress would do that in the same town as Waller since she wanted access to what she knew. But having a crew of SEALs and Task Force X come to pick her up: that's classic her. The Wall can talk about national security until the cows come home, but her deal is that she gets her jollies controlling and, more so, manipulating powerful people...which made the mid-credits scene all the more delicious given my favorite comic cover of all time:

Anyway, the stream of consciousness thing is over for now. I'm sure I'll think of other things to say after awhile.
