I learned my memory can play tricks on me and that this was much worse than I remembered.
I learned no one will make Grease 2 jokes when Maxwell Caulfield appears in something. That amazes me.
I learned Takei can up his scenery chewing, which shouldn't have been possible after Oblivion 1, but it actually happened.
I learned someone can be bored enough to put a map on their own dick and stupid enough to show it to a thieving psychopath who is already pissed off at them.
I learned you can include a mountain turtle for no discernable reason. Or a brother of a dead character for no reason.
I learned the bad ass bounty hunter whose reputation is such that he could kick everyone's ass, can actually do it, which was pleasantly surprising.
I learned Musetta Vander still looks great in assless chaps.
I learned Issac Hayes can be in a movie for no apparent reason.
I learned this was shot back to back with Oblivion 1, in the same way Kill Bill Vol 1 and 2, and Gor and Outlaw (of Gor) were.
