Re- How To Complete The Criterion Collection. What are you missing? Considering you're in the UK (like me) thats pretty impressive. I hit just over 100 before the end of 2009. Is it mainly the OOP titles that you're missing? I went through a phase of picking up whatever I could of OOP titles, paying heavily for the likes of How To Get Ahead in Advertising, Spellbound and The Unbearable Lightness of Being.
