If you have watched Him and Her versions forget about this one. Nothing new and scenes are badly put together. Too many sudden cuts, and changes of scenes and moods, no explanations. If you wonder which scenes are used that are in both movies, here it goes, class- from Him, car- Him, apartment- Her, ending- Him.
Even if you haven't watched first two, skip Them, you really don't need it, and instead watch Him and then Her. I think it would feel wrong to watch first Her and then Him.
And yes, as others here have said, this version is boring, but I have enjoyed Him + Her.
On the surface this film is about a group of people who have been labelled “villains”, working together to save the world. But really, this film is about one man and one man alone, he isn’t strong, but yet he defies all odds and sacrifices his life to save his friends. His only power is his bravery, he is the driver of the van and the main character of this film, Milton.
