Rampage veers between exhausting action sequences and eye-glazing exposition. Characters says lines like – get me the neuromuscular synapse activity. I wanted to interrupt with – get me a good time. But the writing is so lame that even Johnson’s Herculean charisma can’t make this compelling.

We have seen experiments go more spectacularly wrong before. Rampage tries to go one step further by starting with monsters in space and ending with monsters on the ground. But the film then does little with any of its three.

Overall, while the film is a cautionary tale about the dangers of biological manipulation, it offers nothing exceptional that one has not seen in earlier films of the same genre.
