Mark Kermode and Simon Mayo review Avengers on BBC Radio 5 Live.
Here in the UK, much-respected Mark Kermode (he's usually right on the money) likes Avengers and CiTW! CiTW is commented on near the beginning, when going through the top 10 current movies, Avengers review is I think about halfway through. It's live, with a few verdicts from listeners too, all of who love it. No spoilers.
