It started off a bit slow but I think the Sentai Daishikkaku show has found its stride again. Episodes 2-4 kind of fell into a standard "fight against the local big bad guy" thing which I do find enjoyable, but the stakes weren't the same. There were peeks into things happening elsewhere, but due to the abilities on display the plot was focused. It was still very enjoyable in the standard shounen-y way!
Having watched episode 5, I can say that it's really done a great job of re-establishing the things I liked about it begin with. Lots of complicated motivations and factions and some mystery to go with it as well. You can't tell what's going to happen next!
I feel a bit limited on what I can praise about it without spoiling stuff, unfortunately. The visuals are still really good and this studio is definitely continuing to improve on things there.
