One of my fondest memories of TV viewing in the late 60's and 70's, was the weekly hour of tension which Mission Impossible provided. There was the initial bewilderment of trying to work out how on earth the brief flashes of peculiar devices and tension-ridden confrontations could possibly be woven into a coherent plot. Next, there were the wonderfully mundane locations in which Peter Graves would retrieve the briefing materials and the tape which invariably dissolved in a cloud of smoke.
After all the introduction, the remaining fifty minutes was sometimes an anti-climax. More often, it was very satisfying to see the initial vignettes fitted jigsaw-pattern into the plot. Perhaps towards the very end of the series, the plots became a little stilted or physically impossible; but invariably entertaining.
Like most fans of the original series, I found the over-hyped film of the same name to be an facile and shallow work with no redeeming features. I would die happy seeing a film in which Martin Landau, Peter Graves, Greg Morris et al. emerge creaking from retirement to save the day, and as they so often did, drive off leaving thwarted villains to turn on each other.
