Could someone from Scotland please give an appraisal of James Doohan's performance on the accent? I know that there are many regional Scottish accents and certain variations of particular sounds within each, but as an ignorant American I'm curious as to whether anyone in Scotland would actually talk like Scotty. And if it's not realistic, does it sound as if he was striking a balance between authenticity (or possibly caricature) and what he thought an American audience would be able to understand? Or more as if he just wasn't doing it very well? Thanks.
