I know i'm in the minority but I enjoyed Cars 2. Yes, it wasn't nearly as good as Cars but Pixar has really set the bar so high that any lower quality movie even if it's decent is pretty much considered a flop. I'd recommend watching it, just keep the expectations low.
I'm with you, though it's probably because I'm a huge Pixar fan

.
OP, as others have said, you don't *have* to watch Cars 1 to enjoy Cars Land but you will enjoy it more if you did. Cars Land is indeed set between the two films so you won't miss much by skipping Cars 2, at most, just a few sign references in Luigi's Flying Tires queue. But hey, if you have the time, Cars 2 is still a fun movie anyway
For SUPER full enjoyment of Cars Land

, I do recommend watching two more things, if you have the time and means to watch them.
The first is the Cars Toon - Mater's Tall Tales shorts. They're a series of shorts in which Mater describes to Lightning the various different outrageous adventures he's had. All of them (except the most recent two) are referenced in Mater's Junkyard Jamboree across a big wall next to the queue. I get a kick out of that every time
The second thing, again if you have the time (you most definitely will have the means), is the latest of these shorts, Time Travel Mater. It is shown every few min in Blue Sky Cellar and it tells the tale of the founding of Radiator Springs. The stuff in there will be referenced on Radiator Springs Racers, and I'd recommend this one the most just because it's already there for you, and you'll recognize the stuff from it immediately.
Have fun in Cars Land!
