This, a fourth film about the infamous St Trinians school just doestn´t work on a number of levels. Whilst George Cole has been consistently good throughout the series, this movie really needed an actor of Alastair Sim´s magnitutude to make an impression. The few laughs are laboured and it is certainly the weakest in the entire St Trinians canon. Helps pass a Sunday afternoon, I suppose, but offers little in terms of laughs or general entertainment.
