I have always been a fan of the Hercule Poirot mysteries and was pleasantly surprised when I bought "Movie Collection" Set 4. I had not seen the episodes included on these discs and they were very well done and longer than most of the usual Poirot episodes: as advertised, they were "Movie" length. I went on to buy sets 1, 2 and 3 and upon opening sets 1 and 3 was disappointed to find the episodes are exactly the same as the original recordings (which I already owned). These collections are sold using a STRONG suggestion that they are substantively different from the original recordings. I mean, it's only logical to believe they would be. Otherwise, why would Acorn Media sell the collections under the new description of "Movie" length? Why, indeed?
If you own ANY of the original recordings of the Poirot episodes listed in the Movie Collections (with David Suchet), don't waste your money on these: they're the same.
