So many things wrong with this movie SPOILERS

Rating: 6/10 (29 March 2016)

I don't write reviews. This movie was so poorly executed I feel compelled to.
I'll start with the positives. Batfleck was pretty great. Not thrilled with his willingness to kill (more on this later) but overall, I approve of this big, bulky, ruthless Batman.
Wonder Woman is excellent as well. She's strong, powerful, confident, and can stand toe to toe with Superman and Batman.
The score we extremely well done as well. The mood, setting, and ambiance was fitting.
The bad...
The plotting and narrative is lacking on every level. HEAVY SPOILERS below.
My biggest gripe is the motivation for the "big" fight:
So, Lex blackmails SM to fight Batman by kidnapping Martha. Why doesn't SM just save his mom himself? He can fly around the globe in an eye blink, see through walls, and hear a pin-drop on the bottom of the ocean, why not use the HOUR lex gave him to grab her in the 10 seconds it would take him to locate her? Can he only save Lois? He flew from the North Pole to save her from getting turned into sidewalk mush, but finding him mom? Impossible!? I've seen the argument that Lex was watching - or had people watching. Well they didn't do a good job reporting that he and Batfleck hugged it out and left separately, both very much alive.
Why did Batman go save Martha when SM could've done it in a split second without risking her life in the process? It apparently wasn't right away either since he had time to change Batsuits.
Batman Hates Superman because of the destruction caused in MoS? Batman is a smart guy, he knows SM didn't cause that. He's witnessed 2 years of SM doing good. Yet Batman wants him dead, because reasons? I can buy he want's to know HOW to stop him (that's legit Batman) and he wants to know SM's true motivations or hidden agendas, but to just outright want him dead? For what? Even that hack Frank Miller gave Batman ample motivation in the books, and still didn't kill him!
This Batman is willing to Kill. Even to kill Superman. But since this is the same universe as Suicide Squad he's apparently still unwilling to kill Joker...?
Lex keeps the most secure and sensitive data in his home in an unguarded - no cameras, no guards, no locks - server room across from his kitchen with a convenient USB cable for easy data extraction?
Lex hates Superman because.. other reasons? What's his motivation? Power? Lex is a corporate icon, his villainy is blue collar with dabbles in black market arms dealing. Something this Superman seems oblivious too. Superman never paid him any mind until he forced him to. Why? To kill Superman? Why? For what? Because he's powerful? Then why did Lex invite OTHER more powerful Aliens to earth? Because reasons? That contradicts this previously surmised motivation. So what?
Congress isn't sure about Superman because a village in Africa got shot up by the same terrorists that kidnapped Lois...what does this have to do with Superman? Does Congress think HE shot those people?
WW comes out of 100 years of isolation because of a picture? She's in isolation, why does she care if someone has a picture of her 100 years ago if she's not a factor now? She just made herself a factor to prevent a picture of her to become a factor of a non factor....??
WW is there to retrieve her photo, but all she does it take the external HD that Batfleck made, so she just took the copy of the photo. So, Lex still has it. Then Batfleck emails it to her, another copy. Basically she went to get her photo back and ended up just making 2 more copies. Next we see her she's just leaving? Mission accomplished?
Doomsday - Splice his origin with Bizarro and kill him after 10 minutes.
Speaking of killing, you waste an iconic story like the Death of Superman by cramming it into the last 10 mins of this movie, and you already spoil the outcome for the non comic minded by queuing his heartbeat and showing his casket vibrate.
How did WW know Lex had a picture of her anyway?
How did Lex connect a 100 year old picture of WW to security footage of a random ATM machine? Jimmy Olsen - Killed off immediately because Snyder thought it'd be fun?
Mercy Graves - Killed by Lex for reasons...?
The Spear - how did Lois know it was needed to stop Doomsgay?
Why did we need another Bruce Wayne origin scene (thank god it was brief)
