• This film is an exceptional, very challenging and thought-provoking piece of work. Viewing it, as I did, at a morning showing on opening day, however, is not to be recommended. Having said that, I am not sure when the optimum time for seeing this film would actually be.

    There is a lot of very uncomfortable viewing here. The subject matter - such as it is - is very bleak, but, paradoxically, more life-affirming than depressing. That is to say, I looked at the majority of the characters on screen and thought: please don't let me end up like that.

    The plot is thin - that is not meant pejoratively, it's not a plot-driven film - but the performances of the cast simply roar off the screen. Peter Mullan and Eddie Marsan are fantastic, but then again, they always are (as an aside, does Marsan not tire of playing scumbags?), but the real revelation in this film is the performance of Olivia Colman.

    She is perfect in this, absolutely note-perfect; incredible acting. Awesome in her delivery. So good, in fact, that you forget this is just a movie. Her performance here is definitely going to propel her into the upper echelons of British acting - if she is not already there.

    Tyrannosaur is not faultless, there are some scenes that linger too long and others that linger not long enough, but for an early effort from Considine this promises much for the future. This is Considine's 'Taxi Driver' and I will queue around the block for Considine's 'Goodfellas'.

    Superb writing and gritty direction; performances better yet and Colman delivers on every level. Bravo Ms Colman, and bravo to everyone else associated with the best British film of the decade.

    See it.
