It’s about what I expected (I always keep expectations low; easier to avoid disappointment). If anything, there were some extremely promising high points: steering weight and feel, clutch weight, gearbox seems decent enough (not quite GT4 good, but almost nothing is). Tougher to get a read on the chassis; I definitely got the impression that Lotus botched it with respect to providing different (seemingly random) tire and suspension setups to the wrong people, but that’s a strictly perceptual issue.
What makes the Cayman a “better” car is also why I don’t want another one: it does everything well, and therefore doesn’t do anything well enough. 
I understand why garden variety casuals come away impressed with it, because most of them have only (if even) driven bland crap like an Audi RS or F/G-chassis BMW M car and next to those, the Cayman seems alive (without beating them up, which they don’t want or can’t tolerate). To me, though, with a lot of seat time and past ownership of classic Porsches and M cars, which are cars that made you work for their rewards, the first thing I noticed upon jumping into a 991 and 718 was how limp-wristed the steering weight and clutch was, and how muted and numb it was just maneuvering around the parking lot, or really at any speed south of 60 mph. After 30 minutes out on the road my reaction was “evidently fast and well composed but…is that it?”
That said: the GT cars are a bit different, and I would absolutely get another GT4 if I had the storage space to keep it solely for the specific use case in which it was intended: lengthy backroad drives book-ending all-day lapping. I did track it and really liked it in that context, but as an on-road weekend sports car, it wasn’t that much fun at all. But I have zero–absolutely zero–interest in a 911 Carrera or Cayman S/GTS. Similar demeanor at road legal speeds, but even less feedback and precision. To most buyers that translates to a good intersection between comfort and performance, but to me it just translates to boredom.
I think the other comment about Lotus equating to Alfa Romeo is a good one: these are, at least traditionally, cars built by and for eccentrics. Yes, this is a more approachable and mainstream Lotus (a point of some concern to me, and one that won’t be fully addressed until I drive one myself), but virtually all of the reviews seem to suggest it’s still, at its core, a Lotus: watch the Harry’s review where he takes his hands off the wheel and you can see it visibly writhing on its own…glorious. If that’s what you want I can’t imagine being disappointed in it (let alone preferring a 718).
All of this aside: I was never after a FE Emira in the first place. I’m not keen on being a beta tester, so I’m aiming for a second or third year car and whatever iterations are to come, and they will.
