The problem is.... There was only one Matrix movie. =) (Seriously tho, I have the hardbook 1 Matrix movie Bluray because I hated the second two movies, but finally bit on this ultimate collection today via the HTF Amazon link)
As poor as the two sequels were (although the second film at least has a handful of good action setpieces), under $30 for the original film and the Animatrix shorts and all of those extras is enough to get me to upgrade. I disliked the third and fourth Alien movies, but getting the Alien Athology on Blu for under $35 was worth it to me for the first two films and the mountan of extra features (the behind-the-scenes look at the tumultuous production of Alien 3 was far more entertaining than the actual movie). At $50 or more, I wouldn't get the Ultimate Matrix set, but for $27? Yeah, I'll bite.
