What was the "one CGI-heavy sequence"? I'm surprised I didn't catch it. Or maybe I did and subconsciously thought nothing of it.

As for CGI in general, look for my Medium essay "Indiana Jones and His Five Adventures." I have more than a few things to say about the problematic use of CGI, especially with regard to "Indiana Jones and the Kingdom of the Crystal Skull."

As for "Carry-On," I wouldn't say it's destined to be regarded as a classic thriller, but I thought it was very good.
