Good review, tad short though.
These guys are one of those bands I know I should check out but probably won't, at least for a while. As for them being huge, the British music scene seems pretty weird to me- there is an appetite for 'alternative' and rock bands, but the only ones that become huge are often watered down from their past material (Biffy Clyro, Twin Atlantic are next) or have always seemed a bit watered down (You Me At Six etc). I don't really have any faith in the British public to sustain a band's career after the decline of bands like Reuben, Hundred Reasons, Nine Black Alps etc.
