I was genuinely surprised by Millar & Quitely's comic back in the day. I'd grown tired of Millar's shtick by that point, but he really upped his game thanks to Quitely and seemed to have something to say about Superman and superheroes in general with this series. I think the comics delivered diminishing returns as the series continued, but I still held out hope that the Netflix adaptation might be able to reshape it into something better--which has been the case for several adaptations of Millar's comics.
However, I can't say I was particularly impressed with the first episode. I probably shouldn't have been surprised as it was written by Steven DeKnight, who had previously managed to bore me stupid with both the Netflix Daredevil show and the Pacific Rim sequel.
What was truly disappointing is that there wasn't even a single noteworthy action sequence in the first episode. I figured, at the very least, they'd make sure they delivered some eye-candy to grab audiences out of the gate. Nope. All we got was a fairly limp battle between their Mongul-knockoff and their JLA-knockoff.
Of course, the lesson Hollywood learns from this will be that Superman is boring unless he's evil.
