Yeah, I can see why people would like it. But it did nothing for me. I liked the premise of the Thunderbolts being villains who were trying to reform and do right. I liked it when their desire to do right was so completely tied up in their own egos, as with Zemo.
But Osborn, Venom, Bullseye and Moonstone effectively using it as a form of immunity? That really didn't do it for me. In fact, the only bit of that run I liked, at all, was when American Eagle crippled Bullseye.... Except, of course, he got better.
