I mean, it's been a couple decades since I watched this show, but there's some very non-star trek type stuff that eventually happens and really detracts from the quality of the show (side character story arcs mostly). Might want to find a guide to skip those non-essential hairbrained episodes. Though I think DS9 had one of my favorite cross-over episodes where they do a time travel and participate in the classic Trouble w/ Tribbles plot from the original Star Trek.
