There is an astounding level of ignorance displayed here, and, dare I say, [censored]ery also. I expected better on a discussion forum which I thought would attract discerning and educated drinkers.
Some facts:
Lagered beers are a style of beer named after a process. Nothing more or less.
The commonly available lagers in the UK are mass-produced rubbish from globalised companies trying to maximise their margins to thrill their shareholders.
There are plenty of fabulous lagers in this world, and the history of lagered beers is as rich in heritage and tradition as that of "British" ales that no doubt those knocking lagers are so proud of.
In the UK it is possible to find "good" lager beers. Many new craft breweries are making the stuff, and there is at least one independent specialist importer of Czech beer in the UK (Pivovar in York, who will happily sell you a keg of delicious unpasteurised Bernard). The most accessible Czech lager in the UK is probably Pilsner Urquell. Bottled, and in most supermarkets, it's surprisingly faithful to what comes out if the tanková on the streets of Prague, though it too is now succumbing to globalisation and quality is dropping. Hell, even the notorious Staropramen (which most Czechs poo-poo) is like a thunderbolt of taste compared to British mass lagers.
As to the original question, I think there is space in the UK for a great and faithful Czech style lager. The craft brewers in the UK tend to make what they call "bohemian lager" with too unsubtle a taste (what they're good at in ales, but what isn't necessary in lagers!). Czech beer is very subtle in taste, but still a million times tastier than the Carling etc we've had to put up with in the UK precisely because of the misconceptions shown above about lagers.

PS I've been a little Czech-centric here. It's just a personal preference. I've also had great lager beers in Poland and Lithuania. I understand that now even Germany is making some good beer! :)
PPS Cask-conditioned lager? I think that would lose all its carbonation or make it a nightmare to handle. But they can put men on the moon these days....
