I hate to say but I agree. Eric Wallace did good in season 6A, but otherwise his role as The Flash showrunner is not exactly one I'd bring up in Arrowverse conversations. While pep talks aren't bad, to have less action in the span of a season is not what many comic fans sign up for.
6B-7A have not been great, and while I'm cautiously optimistic on 7B, I'm not expecting my opinion to change. Unless the remaining episodes (including 150th milestone episode) change my mind, Season 7 may potentially be the worst season of The Flash...yes, even worse than Season 5. But I'm not saying that will be the case just yet, just possibly.
For the record, I think cartoons can be hit or miss, depending on the series in question. Harley Quinn is an alright series, it's nothing to be taken too seriously, I think...though the DCAU fan in me loves that Michael Ironside returns as Darkseid! Of course overall, I rank the DCAU animated series above all DC universes. Before the Arrowverse, the DCAU brought bringing comics to life while referencing the old first, and done really well...DCAU is literally perfection.
