A quite delightful film and worthy of an Oscar nomination for the acting skills on display.
Essentially it centres around a lone parent bringing up his six kids in the wild while his wife is being treated for bipolar disorder. He trains his kids in all areas of survival, home schools them (to a ludicrous level with only books as a source, but we'll let that slide) and treats them all equally despite differing ages.
After the wife dies he is ordered by his father-in-law to keep away from the funeral but he packs up the family into their bus as her will states she doesn't want to be buried.
It continues from there with plenty of implausible scenarios but overall it wins as it is a feelgood film and it puts a smile on your face. Watch this movie and you won't miss the two hours at all.
