I think, given that both sides are complaining about being attacked, the media probably aren't actually that biased overall.
However, what I would much prefer to see is much more moderate coverage of the different political parties. However, that would require that the political parties make moderate claims about each other, rather than just painting the other parties as the devil incarnate.
At the moment, media coverage of UK politics is dominated by outrage. I get it, outrage sells news stories to a very large proportion of the population. It puts me off, and makes me distrust the news. I'd like to see more "We think this policy would be best because..." and less "OMG the other party are killing babies as we speak." Social media does not achieve this.
