So far, all of Anderson's films on Blu-ray have looked pretty damn fantastic. Even the oldest, Bottle Rocket, had a superb transfer. Of course, it doesn't hurt that his oldest film is only 16 years old. Still, plenty of catalog titles on the format from the mid 90's look like crap.
The Royal Tenenbaums is easily my favorite film from Anderson and with the price cut to $19.99 thanks to Best Buy, it's an incredibly easy day one purchase for me. Can't wait to get my copy.
