Short version: Very enjoyable. It had great action, some very funny moments. solid espionage plotting, and surprisingly fine acting. I think that this movie very solidly puts the franchise back on track. And may do the same for Tom Cruise's career.
The things that have been seen are movies. Because, fortunately, they still can't be smelled. Or tasted. I then talk about what I've seen, and whether or not I regret seeing it. And whether you should see it, too. Some people would call that "movie reviews", but they've clearly never been paid by the word.
