THE SHORT VERDICT:
Show starts out pretty strong, with an interesting premise, a big budget and a promising cast. Production values are suitably high, and I found the scenes of a dystopian Seoul particularly impressive.
Jo Seung Woo and Park Shin Hye are both solid in this, and they are supported by an excellent secondary cast. When viewed through a comic book, space opera sort of lens, and without too hard of a grip on logic, Show manages to be reasonably enjoyable and entertaining for most of its run.
Unfortunately, the ending was not my favorite thing about Show. Admittedly, your mileage may vary on this point, because what bugs me about the ending might not be an issue for you in the least. If you like the ending more than I did, you’d like Show a lot more overall, as well.
