It looks good, I do appreciate that the colour pallette has brightened and that they have more focus on story and humour. The return to Themiscyra was unexpected so soon and Steppenwolf looks good.
What concerns me is that they haven't learnt the rule of "Show don't Tell" - don't try and convince us that Superman was a Beacon of Hope, when nothing he did in either MoS or BvS was particlarly hopeful or inspiring - it's the same problem they had in Suicide Squad when they kept saying the Squad was "Worst of the Worst" but none of them did anything particularly Evil
and I do hope that Batmans apparent man-crush on dead Superman is just over emphasized in the Trailer and doesn't become a key trait in the movie.
