Journey 2 was a massive hit.

Made over 300 million worldwide and the budget (minus advertising) was only 79 million.
Rock got locked in a bad deal with Disney... but he's been a pretty consistent ticket pusher when his movies come out.
Yeah, I thought I remembered I being decent worldwide. Likewise, in the US, it wasn't insane. Although $100 mil... Okay, I guess I was wrong, that is impressive. I thought it did about $30-40. So ignore the Journey 2 ignorance.
That said, I still wish Rock would return to R rated action. It's what he was born for.
