Well, first things first. Ottomans helping German's to build chemical weapons was a complete bullshit ww2 propaganda for typical lowly educated English speaking masses, with the context of ww1.

When you check the facts you will see, actually, Turks got hit by Italians chemical bombs. Then the widest and mass usage of chemical weapons was British using it against Russian Bolsheviks.

Furthermore, there was no plan or what so ever like preparing an attack with chemical weapons to hit allied forces, especially from German's nor the Turks. This is purely designed for those typical Trumpians, and you know Bible readers.

Let's get to secondary issues such as how would the most gullible character of DC comics come alive. Why would cheap action figures exist in the movie? You know when you spend quite a lot of money into a production like this, you would want the CGI stuff to look professional rather than cheap. But there are many scenes that you can pick.

Deflecting bullets with those arm protectors, not cool at the very least. You know it's not the arm protector, its the design of the scenes, you can do it once, twice, but man, in every scene deflecting bullets like you wipe some sweat from your forehead. That's not totally cool.
