I like Alex because I think he is quirky and interesting to watch.

Part of the problem about this year's Big Brother, for me, is the lack of a diverse range of characters. They're all much of a muchness.
One of the interesting aspects of Big Brother is how people from different backgrounds react to each other and how housemates change in each other's company.
Alex stands out because he is a very different character to Jonny, PJ and Spencer when he was in the house, who are all typical lads.

He was very much the underdog in the first week when Jonny and everyone close to him were against Alex. I think many people thought that he looked like he was being bullied and they found this endearing.

Although I did quite like Spencer because of his quietness and unwillingness to get involved in the games at the beginning which I thought were false, I did want to see Spencer evicted instead of Alex.

Bubble from BB2 said on RI:SE the other day that although you might prefer to know or live with Spencer, Alex is better to watch on TV and I agree with this.
