No.
The wait for MIB in the afternoon is 1 hour. People do that ride over and over to get a good score.
The new field trip destination is IOA, taking that title from Disney. You'll see lot's of schools there on a Friday. But US is still busy.
If you have multi-day tickets (both parks), the idea is to hit IOA in the morning, then US in the afternoon, then back to IOA as the wait times drop back down and the field trip people leave.
These people only go to IOA, so you can go to Universal in the afternoon when IOA becomes gridlocked (1 hour waits).
The attractions at US, although not thrill rides, are still interesting to see, and their play grounds are fun for the kids, like my 9 year old daughter.
