Interesting construct....
Is there any connection between "scannán" and "scanrúil"?
If you wanted to say, "That film was nice", would it be "Bhí an scannán go deas"? Not exactly sure when the "go" prefix is required and when not. "Tá an aimsir go deas" "It's a nice day" prefixes "go" to "deas", but I'm not sure of the rules that require it....
