Starting off this *is* the writing of an oft-favoured 1980's B-grade fan, so I am in no way writing this to compete with previous reviewers or take some imagined review 'injustice' into my own hands.
I appreciate the plot line as a particularly classic one and with its means to expand on whatever drama or storyline unfolds the end result is what you get. Its the whole 'put in an overseas jail' thing. Yes, 'purgatory'. So my comments are really relative to people who like me who enjoy a little cheesiness. No you wouldn't see Meryl Streep in a movie like this one and thats what gives its character.
Take bits and pieces from the movie. For me they are dazzling scenes occurring by the minute. No matter what they say it all seems to wind up funny to me. No matter what the musical soundtrack is, it always manages to impress vintage cheese upon me. I am about to write up some quotes so check them out. Thy might give you an idea of what you're in for.
