Make sure to come here EARLY. The place is free, so unless you booked online (with a waiting list of over 2 months), you should come here before they open. Otherwise you will indeed have to wait for quite a while under LA sun.
Great modern art inside, I would definitely recommend it to family and friends coming to LA. Overall the museum can be done under 2 hours, unless you are on a waiting list for an exhibition.
