The technical side of things are good, but certainly not great. It is, most definitely, a clean print, and one with enough detail. However, there are a number of nighttime scenes, and in them all the blacks meld into one another. Regularly, it is impossible to tell where the background ends and a suit begins or where hair ends and a blouse starts. Whether this is an issue with the source material or the transfer I can't say, but it is disconcerting to watch. The DTS HD 5.1 MA soundtrack, like the print, is clean, but it isn't as full or rich as a bigger budget production might be. There is in fact one scene where the room tone and voices seem to change mid-scene. It is all okay, and I don't know that with a minimalist budget for a film that was quickly shot there is much more available.
Vardalos and Corbett describe the making of the film and its success as something of a once in a lifetime deal, one where all the pieces just came into place. Zwick is an excellent director who had a great cast and a wonderful screenplay. In short, My Big Fat Greek Wedding is one of those romantic comedies which is, beyond a shadow of a doubt, well worth one's time. It won't change your life, but you'll smile and laugh.
