I liked Alphas, but as I recall, I didn't like season 2 quite as much as season 1. The show was originally run by DS9's Ira Steven Behr, but in season 2 he was replaced by Bruce Miller of Eureka and The 4400. The season 1 finale set up a major status quo change that excited me, but the season 2 premiere unconvincingly hit the reset button on it.
I liked how it was generally a relatively realistic treatment of superpowers. The Alphas didn't have physics-breaking fantasy powers like flight or teleportation or shapeshifting, but more plausible powers like enhanced strength and senses, enhanced learning abilities, etc. Sometimes the powers got implausible, but not as often as usual in series about superhuman characters.
