Brightburn is one to watch. It has a beach. Widne risk swimming in the water though. Town centre is a bit run down. It's just your average seaside town tbh. In saying that I haven't been in Ayr for years. It could be the Scottish Monaco for all I know.
Tried the John Wick films? Found this review The 'Wick' films are best not appreciated not so much as story but pure choreography, albeit one in which the dancers are stabbed in the eye socket. Leon was absolutely brilliant.
They stopped making them in the 70s and most of the people involved are dead which is pretty final. Give them a go.
I liked the start of wick 1 when they kil his dog but then it got silly.. It would have been a top film if he was just a regular guy out to avenge the death of his dog
