Alphas looks like Heroes redux. Plus it being a SyFy show makes me think it won't be worth watching.
From what I've heard, any similarity to Heroes
seems very superficial. Also, the showrunner is Ira Steven Behr (Deep Space Nine, The 4400
), which means it should definitely be worth checking out.
I didn't like The 4400 or his work on that. I did enjoy a lot of the things he did do on DS9(the arcs, the Dominion War stories) but I hated Vic Fontaine, the Ferengi stories, the Jadzia/Worf romance, the wasted potential of the Federation/Klingon hostilities. He is a very hit-or-miss writer.
