The rating isn’t indicative of the movies but instead the discs are the same from previous releases and only DVD with films 2-4 did previously get Blu-rays. But on a budget, and if you don’t already own them, this is worth picking up.
The Trip to Italy is not for everybody as it is basically two guys chatting it up, while eating mostly pasta and drinking wine, for 100-minutes, but for myself, I enjoyed the banter between Steven Coogan and Rob Brydon and the travelogue-like plot taking in the sights of Italy is worth the time.
