Re Picard's alluding to current events (Romulans = manipulative Russians or hapless Syrian refugees, Federation = Trump's America) - well they did that in TOS too, often with less subtlety! In itself I don't see that as a bad thing at all, it depends on how well it's handled. Maybe I have a low bar for SF following The Last Jedi, but I thought Picard did a pretty good job. I liked how they rooted so much in the lore, so that even the suddenly multi racial Romulans could claim ancestry in Voyager's Tuvok as well as in the wildly varying past depictions.
