I'm always irritated by Trek crews fascination with the past via the holodeck. What a yawn. You know how sometimes it's not a holodeck story but there is a holodeck scene in it from which Our Heroes are seen briefly enjoying themselves before red alert sounds.. well WHY couldn't they have given us just once a really cool scene of non-human history or history which is our future (WWIII story) or ANYTHING but the endless period costumes. They could have added to Trek lore with some nice tidbits there. If I had access to holo stories I wouldn't waste one second on earth history stories.
