What on earth was Jeremy Irons thinking!?
Very lowest-common-denominator stuff here for those with scant understanding of humour. Grumpy gleefully obnoxious father and uptight son are forced on a road trip...you can see the formulaic story arc from the start.
Sky Movies gives it 4.5 out of 5 stars - not a very discerning customer base I'm learning.
A half hour down and an hour to go. Give it a miss folks.
