This show is clever and shockingly funny. Even after three seasons it's still entertaining with well-developed characters. Season one drew me in quickly, had an interesting story arc throughout, and I purchased the DVD as soon as it came out (as far as I know it didn't come out on BR).
I was surprised to find that season two was even better, IMHO! The over-arcing plot was more enthralling/world-building, the humor was more satirical (which I liked), and we really get to know the characters well.
The third season was a few steps back in my mind. The antics of Black Saturn started to wear on me, the odd couple(s) match-up was fun at first but didn't really go anywhere, and after a mid-season return (which didn't happen the first two seasons) the pacing from the first half seemed to have lost steam.
Overall, this is a great show that I feel many fans of superhero and/or satire comedy will enjoy. There's also an impressive list of voice actors for the show that may surprise some people. I don't know how popular Crackle is, but with it's several original shows and movies, as well as its regular programming selections, I'd say it's better than Hulu in some ways; least of which is that it's free.
