I'm not saying Robson Green's Wild Swimming Adventure is a bad show. What's not to love about a small geordie swimming across things he shouldn't swim across, then crying about it afterwards? It's just that when the title flashes up on STV without the trailer, it sounds... well, crap. Unless you're a massive Robson fan, I suppose. But somehow hearing his name doesn't have the same connotations as Bear Grylls, or that other chap who fannies about in the wilderness whose name I have temporarily mislaid.
An aquatic adventure I would not hesitate to recommend, on the other hand, is Shark Swarm. There are sharks, and boy do they swarm. Thank you, Sky 3.
