I saw BLACK ADAM. Don't get the dislike I've seen online, honestly. I thought it was a fun use of the modern Black Adam. The JSA get just enough so you know who they are and are pretty well realized.
I'd quibble that Dr Fate's realization probably owes a little too much to movie Dr Strange, but he's fine. Hawkman reminds me a lot of Geoff Johns' run (in fact the movie itself reminds me a bit of John's JSA period that included Adam). Cyclone's powers are well realized and Atom Smasher may be wearing his modern outfit but the characterization is early Nuklon from Infinity, Inc. where he was a bit of a clutz.
Sarah Shahi is good as the normal person who grounds the heroes in the story.
Story is kind of serial like, as it rolls from action/fight to action/fight. I don't think anyone will marvel over it, but it gives you what you need.
