As a standalone, this "movie" was pretty fun and engaging, for the most part. But as a part of Smallville, it's a bit problematic. We're 11 episodes into possibly the last season and they're just now introducing these huge plots. The show already does a crap job of showing what Zod and Tess are up to on a regular basis (instead, we just hear about it after the fact) and now there's Amanda Waller and Checkmate to add to the off-screen goings-on. You know what this means? Get ready for even more exposition where characters talk about interesting-sounding things they've done but that we never actually get to see. But, like I said, it was mostly fun, which is rare these days for this show. So... thumbs up.
