Explorers is a brilliant episode! It's not as politically far-reaching as the previous two episodes, but it's an excellent exploration story nevertheless. It's good for the Ben/Jake relationship, good for Sisko in general again to be having more devlopment, and of course it's good that his goatee has finally joined the rewatch thread! Our pagh is stronger for this.
It's not perfect by any means, but it's a joy to watch. And I love that fireworks scene, even though it's just a tad random. It was the perfect end to the journey.
