The UK (and the US) do have a hyperpolarization in their political system. This polarization is result of the way the system has been designed. While a democratic system this lasting is impressive, it is clear that those systems have been devised before mass media was a thing, which is filled by particularily bad actors both in the UK and the US (maybe because it is much easier to do populism if to every issue there are two sides).
Having two clear sides has also certain advantages, e.g. it is more comfortable to think about a world where the complexity is reduced to two factions. This is why Hollywood traditionally made clear division into good and evil, until they started to experiment with more complex representations of reality.
Not that polarization isn't an issue in Europe as well, but it is nowhere near as backed in as it is in the US (and quite frankly I am not sure the US doesn't play a involuntary role in this polarization at least since the cold war).
