Call me old skool, but Legos were my favorite "toy" growing up and those sets were far more "generic". You build anything and everything, not just whatever a set was designed for... that kinda came later. Anyway, it is more fun and educational, using your imagination than it is just building a predetermined "model". I spent endless hours making stuff.
Don't get me wrong, I am a super STTNG fan and think this kit is awesome. I mean, it even has Spot! (But I also won't be forking out that much money for some plastic blocks).
First, Lego sets were never "generic". They were exactly what they were, be it a truck, a house, a castle, a space ship, or a dog.
Second, today you build anything and everything. There appears to be one new/unique part in this set and it's a very useful one. Take a look at Rebrickable.com and you'll see that there's a truly massive trove of other things people are making out of today's Lego sets. There was a brief period around the 1990s where there were a high number of elements that could only be used for what they were. Bows of boats, noses of airplanes... whatever. But for a very long time that mistake was remedied and things tend to be brick-built now, out of smaller, more useful elements.
Yes, there is a newish adult collectable trend where people can buy things like this for display purposes but I absolutely guarantee tonnes of these sets are going to be ripped apart and incorporated into other things, and in many cases the parts sold on the secondary market to become something completely different. I have personally bought tens of thousands of elements that are now on display at home and in my company office as completely different creations. I'm in my 50s and I've got multiple projects on the go, and I'm frequently dabbling in Stud.IO, designing stuff digitally.
The nostalgia you're kind of yearning for is absolutely, positively alive and well, rest assured.
As for price, well, yeah. But this is a 3,600 element set that is licensed. Parts on the secondary market go for between $.10 and $.15 Canadian and this comes out on the upper end of that, but again, it's a licensed product so it's not just LEGO who gets a slice of the pie here. It's still not abnormal. It's just a high quantity of parts. The per-part value is high but not abnormal.
