Becoming one of the biggest comedies of the year Ted takes a great concept and then marries it to the style of it's creator Seth MacFarlane...........so if you dig his humour (Family Guy, American Dad) then this will be a blast and if not then it maybe won't.
A good cast led by Mark Wahlberg and Mila Kunis and excellent visual effects to create Ted made this absolutely hilarious for me when I saw it in cinemas and again recently. However, I do wonder if after a few watches when some of the more outrageous jokes and one liners have worn off whether I would find it as funny after a while.
It might be better as a rental first if you aren't sure you would like the humour on offer as it is pretty adult and broad at times. But a lot of the jokes do hit the mark.
