The song received positive reviews. The AV Club says that on "Be OK" and "Let's Rock," Michele plays the upbeat B-girl over Will.I.Am's anthemic boom-bap. AllHipHop has this to say about Be OK:
I Am is the antithesis to any of the albums currently playing on iPods across the land, particularly those drenched in love-scorned tracks and painful riffs. This is a hopeful compilation of songs. Even when Chrisette seems to show the slightest trace of falling apart, it’s still encouraging. Take the Will.I.Am collaborated “Be OK,” where she claims that she doesn’t need to cry when leaving her man.
At the beginning of the music video, Michele is quarrelling with her boyfriend and tells him to leave and continues in to her car driving off to the mall. She is at the mall with her friends shopping and seems distraught about her breakup. In the video, she is also singing in a black blue silk dress away from the scenery. Will.i.am doesn't make an appearance in this video but instead was replaced another verse by Chrisette Michele. Persia White makes a guest appearance.
