You know, in the end "de gustibus non est disputandum". I'm not sure whether having discovered Cary Grant recently plays such a big role in whether you like a movie or not. It's probably more important what type of movie speaks to you.
You could try Notorious, and the Holiday - two very different specimen - and see which side you're leaning towards more, for instance.
Thank you. Totally agree with you.
Happened to see both Notorious and Holiday over the last weekend and thoroughly enjoyed both.
Did you see "To catch a thief" yet? It's with an older Cary Grant but still one of my favorites.
Recommended Arsenic and Old Lace weren't enjoyable at all (Grant played amazingly though), but the Philadelphia Story (best movie I've seen in years), Charade, North by Northwest, Father Goose - those are amazing masterpieces which I enjoyed a lot.
