Re: antidemocratic etc
The UK has an entirely appointed Second Chamber
Which has a revising and advisory role. The parliament act makes it absolutely clear that the commons can always override the lords.
They do provide a safety valve, though, for when passions get inflamed in the commons. They can delay things until tempers cool ... or prevent something unpopular getting put on the statute book by a doomed and vengeful government that's out of step with the public and soon to face an election or lose a vote of no confidence.
