What can I say about Avengers: Infinity War? I'm genuinely asking: What, this early in the film's run, can I possibly say about Marvel's rabidly awaited comic-book adventure that wouldn't somehow be deemed a spoiler? Maybe it's best to begin gently, not by reviewing the film, but by reviewing the audience. Because even if I didn't enjoy what transpired on-screen – and I generally did, and quite a lot – the crowd reactions at my sold-out 7 p.m. IMAX screening on April 26 would've made the whole experience worthwhile.
