Super duper film.
Think it's based on a true story because a lad I grew up with in 1982 was just like him, he loved watching Lovejoy on Sunday night after he polished his school shoes and before bed time witch is a bit of a giveaway now I look back.
He didn't fight with his step brother though so I think they made that bit up, but that's ok cos it makes for better viewing.
All in all I'd give it 10/10 for comedy value and 8/10 for reality because he didn't fight with his brother in real life as much, so that probably comes out at 9.5/10.
Thumbs well and truly up.
