Clint Eastwood did it better in Kelly's Heroes.
For me, the derogatory way the SAS was treated in the film was quite uneccessary.
The SAS is the longest active special missions unit in existence and has a more gruelling selection process than the Navy Seals. So, the idea, which the film suggests, that the SAS would mess up and that 2 navy seals could beat up 3/4 SAS soldiers is ludicrous.
Typical American 'We're the best ' movie really. Yawn!
