Thunderbolts is currently the film playing in English near me (next week there will be none). I had a look at the trailer and it turned me off as it looked like it was going to be like some bleak piled on top of bleak DC movie, but then I read two positive reviews so I went to see it on Monday (May 5). It was not bleak. The humor was good and so was the plot. Julia Louis-Dreyfus was great as the kickass slippery as hell, scruple-less villain. The whole cast was great although the Red Guardian started to grate a bit in his role as doofus.

TLDR: worth seeing.
