I honestly disagree with the whole "Ezra is Barry in Name Only". While Ezra Barry serves the same purpose of JL Wally(the rookie/comedic role), He definitely seems like he is playing on the core Barry characteristics in a Ezra fashion(how Barry is always fashionable late in the scene with Commissioner Gordon, his fanboy/comic loving persona, the absentmindness, the scientist, and his everyman nature).
I think it's always interesting in Barry is depicted as having a sense of humor, they assumed they take that element from Wally(I can see elements like the overeating, or speed force since that is specifically objects created during Wally's time, but they seem to act like Barry is a character completely devoid of humor, as opposed to creators taking some of Barry's elements and finding new ways to modernize/expand on his character). I always keep getting reminded of this quote by Greg Weisman:
While a good description of Barry's personality and his sense of humor would be this:

While I do agree not every scene hit like Ezra intended, and can feel forced(I did groan at the bat signal scene but loved the "I'm in/I need friends" and the scene with Commissioner Gordon), I think it is Ezra more imbuing himself in the role if anything. I can't see Wally in cartoon or comics, being the first to eagerly join the Justice League simply because he needs friends, or being the last to run off feeling that League running off without saying a word is "rude". The sense of humor might be similar, but the personality behind it is completely different.
I agree with the above post, despite all the arguing and disagreeing with each other, there should be no reason we should at least be amicable and not result to belittling each other in order to get our points across. We all care about the material the companies in order to create these adaptions. We may agree or disagree if the adaption is warranted, but at the end of the day, the discussion always makes it fun to talk about.
Honestly I think the costume works, especially after seeing it in action with the trailers and clips. I feel like just like the Flash tv series costume, it takes the New 52 costume (and in some sense the Injustice look) as the basis for it's design and tried to build on the ideas and look created there. While the tv show took the look and adapted in one way using a more leather design, Zack decided to flesh out the idea that Manapul and Buccellato started that Barry used multiple metal plates in order to conduct the Speed Force energy that the Flash costume is composed of. (Only with metal used by NASA space shuttle and high-tensile wires to conduct the electricity).
