I watched this the other day on demand- it was six in the morning and it sounded mildly amusing without having to follow a plot.
I was pleasantly surprised. The filming is annoying in places when Alastair films on his webcam, but the script was very funny, the acting was OK and the characters were engaging.
The story was slightly bizarre, as kids programmes often are, following Alastair Fury and his friends 'the revengers' as they plotted revenge against his family for the various slights and indignities they had forced upon him. Invariably these 'revenges' came back to haunt him in a comical turn of events leaving him in a worse situation than when he started.
I was a little perplexed why they were calling the sister fat, when if anything, she was approaching skinny- don't want kids thinking they should be thinner than her, they'd be wasting away- but it wasn't a major issue.
I'd recommend it to anyone with some time to kill, it's quite entertaining (in a kids programme kind of way)
