Paul Krugman likes the action, and especially Gordon Brown's leadership (a name not often associated with that term). You should listen to Krugman. He's a Nobel economist now.
Krugman writes that the US plan has been fickle and slow, whereas
the British government went straight to the heart of the problem — and moved to address it with stunning speed. On Wednesday, Mr. Brown’s officials announced a plan for major equity injections into British banks, backed up by guarantees on bank debt that should get lending among banks, a crucial part of the financial mechanism, running again. And the first major commitment of funds will come on Monday — five days after the plan’s announcement.
