On a weekend when nobody deserved to win, it was Transformers: Age of Extinction that beat out Melissa McCarthy's Tammy at the box office. 

The fourth film in the Transformers franchise made $36.4 million in its second week, after taking in more than $100 million in its first week. The film is still on track to overtake Avatar to become the highest grossing film ever in China. It has already earned $134 million there, The Associated Press reports. 

Tammy, a road-trip, gross-out comedy, brought in $21.2 million in its first weekend, which was was way below what was projected. It opened Wednesday, and has so far grossed $32.9 million.

Deliver Us From Evil was in third place, bringing in $9.5 million in its first weekend. 

The summer 2014 box office is way down a hefty 20 percent last year, partly because the July 4 weekend was so slow. American ticket sales are at $2.3 billion for the summer so far, compared to $2.8 billion for the same time last year. 

That could change though - Dawn of the Planet of the Apes (July 11) and Guardians of the Galaxy (Aug. 1)  both come out soon.
