I have never really been a fan of Chris Morris, however given the subject matter of this film, this had the potential to be comedy gold. On the other hand, in the wrong hands this film could have been just plain offensive in the extreme.
There will still be those who are offended by this film though, without a doubt. Perhaps by those who take the film in another manner than which it is intended or perhaps by those who have been indirectly affected by acts of terrorism and find a comedy of this nature in the worst possible taste.
I would urge you to give this film a chance. However, if you find the basic premise of the film grossly offensive and not in the least bit amusing - don't watch it, simple as that. I doubt this film will change your preconceptions.
There are serious undertones to this film of course, in respect of those who latch on to negative interpretations of parts of The Qur'an/Koran and of the true nature of fundamentalism. I can't help but think that the message which Morris strives to achieve hasn't really hit home by the end of the movie though. I think he should be applauded for attempting this however, rather than simply making a farcical slapstick movie about Islamic terrorists, with no thought for what he is in fact trying to say. Beneath the explosions and the silly lines, there lies a dark satire, one which has never been attempted before on this scale.
So, to the comedy then. The first laugh isn't long in coming in the film and the subsquent laughs come thick and fast for the duration. Some may recognise Kayvan Novak aka Phone/Facejacker who has top billing here although plays a relatively low-key role. Some of the best laughs however come from Nigel Lindsay as the moronic "Lets bomb the mosque!" Barry. The term 'laugh out loud' is certainly an overused description when it comes to comedies. However, I defy you not to roar with delight at some of the moments in this film. Some of them are pure Monty Python, I kid you not.
The film does kind of peter out to its logical conclusion by the end, however by that point you will no longer mind. This film performed relatively poorly at the box office, but who knows? This may well be a cult classic in years to come.
