Quatermass was pretty cool. The British films never got as much distribution in North America, but they tended to be a bit more serious and convincing in tone, I think. "Gorgo" was one of the better "big lizard" movies, for instance. British monsters naturally must always gravitate toward London, taking special care to go after London Bridge, Big Ben, Picadilly Square, and such prime locations. Your average monster is just another type of tourist, it seems, stopping in at all the obligatory sites. No British movie monster has ever assaulted the city of Hull. It's clearly not worth bothering about. ;-)
