The system seems to be set up for failure
For a starters the first past the post system where you need 50% of the seats not 51% of the vote to take charge.
A system that has created 'safe seats' for the big two which no matter how shit those 2 parties are they will get back in 99% of the time.
At the same time there are seats which are one or the other so the muppets in the constituency will change sides depending on how the last government did - Blair & Thatcher Legacies mean nothing to them.
Then of course the fact that as soon as a party gains power they are appear to be concentrating more on working out ways to make sure they stay in power rather than actually trying to carry out their election promises. Anything bold or inventive in their manifestos is chucked out the window so nothing ever really changes.
Like it or not the UK has a 2 party system just like the Yanks do. The only difference is at least the likes of Obama only get a maximum of 8 years in charge - 4 years to pander and play safe to make sure they get re-elected and then 4 years really pushing all the inventive, bold and in some cases controversial stuff without the pressure of working our your next election campaign.
If we are to stick with the FPTP system then it really needs a rule that a Prime-minister only gets max. 2 terms in charge. Perhaps we might see some improvement.
Personally I want to see Proportional Representation. but thanks to the propaganda campaigns and poor understanding of voting structures in the UK Public that will never ever happen.
