Mr. Glass to Dunn 19 years ago: ...for some reason, you and I react the exact same way to water. We swallow it too fast, we choke. We get some in our lungs, we drown.” And in Glass, it’s made abundantly clear once again that water is Dunn’s weakness.
Yeah, it sucked seeing that happen to David (that was surprising even for an Shyamalan film), but not everything can end spectacularly even for characters we believe deserved better ... just let the unoriginal and snooty superhero/Marvel haters tell you that. Ai yai yai..
(that was surprising even for an Shyamalan film)
Shymalan was tapping into his inner George RR Martin there.
