I liked and didn't like Ocean's 12. Well-done movie, but what I most love about th' first was that...th' whole plot revolved around th' one thing. It was...simple. Then they tried putting a real plot in th' sequel. ><
Kinda th' same thing with Pirates. First one was awesome, second one had a different focus. (*coughcoughjackcoughcough* Not that I don't like him as much as th' next person)
For the most part I've found that I don't enjoy sequels nearly as much as their predecessors. There's a few that I've enjoyed more, but I can't recall any of them at the moment. ><
I liked all of the Lion King movies. About equally.
I know there's one or two sequels I enjoyed more than th' original movie, but I just can't think of 'em right now. ^^"
