Far better than expected!!!
Ok this definitely is not the Hangover nor is it completely a modern day version of Planes, Trains & automobiles.
Instead you get a mix of the above with a little extra - not a big fan of Zak however this is probably one of his best films to date - you do rightfully in places sympathise with his character.
Robert Downey at start really seems to have the Steve Martin ordinary guy - having a really bad day which just gets worse as in planes, trains etc
However though I really was in two minds over first half hour it really got going from then on in.Could have done a little without the language in places -unnecessary
But thanks to the honesty of the acting some touching moments from both Downey & Zak it's easy seen why this is a great comedy & road movie!!!
The scene at the Grand Canyon especially & some nice scenic backdrops along the way reuniting Downey with Jamie Foxx also good idea!! Plus refreshing change seeing Downey in this sort of character & not iron man!!!
Overall well worth renting or even buying & it's a road movie with a great heart, some crazy moments & understated performances from both the leads.
Plus nice soundtrack to go along with it!!! Hence it does indeed earn a four star rating!!!
