Ok, this wasn't terrible, but it could have been better.
I think the most important thing is to actually make a point with your documentary. Even with short things like that, you still need to have a point driving the way the film is made. There you were simply presenting the audience with basic information (that 99% of people already know) and then finding out what the public think (which no one is particularly interested in).
For a political documentary it's really easy to get interviews with MPs, counsellors, MEPs, parliamentary candidates, campaigners, pressure groups, business owners, local celebrities...etc. If you are going to be interviewing people you need to make it so that the audience is genuinely interested in what they're saying. What we're getting at the moment is just Mr.Joseph Bloggs who doesn't know much about politics, saying that he's going to vote Labour. Instead lets get Mr.Joseph Bloggs, proprieter of the local public house, to tell us about what impact the election will have on alcohol laws. It's all about targetting your interviews to a specific end.
I agree with what people have said about getting your guy out of the picture. For a short, informative documentary like that you don't need anyone on screen, especially not for onscreen narration. Having an onscreen presenter is the luxury of investigative documentary making, and your documentary isn't investigative. It just makes the whole think look a little vain, which I doubt was your intention.
But there was plenty to like. If it had been snappier cut that could have been a really solid couple of minutes of vox pops, but on it's own it doesn't really stand out as a documentary. I would urge to consider re-cutting that footage down and going out and filming a second part of the documentary, asking, 9 months on, what people think of the situation and whether they regret the choices they made in May. That will give your documentary a thrust that it was lacking and could actually be a genuinely interesting piece of film.
Oh and Murdock, you make me laugh
