I also feel the same. The first infamous is my favorite. Second son felt good to play but the story was so nothing, the retconning of the prior games ending really bugged me. And the bosses were so damn lame.
i enjoyed first light a lot, so i was happy to see that second son was up for 10 in the store today. my sunday morning impulse buy. downloading right now. two years later and still a stunning looking game.
