Natashavj’s review published on Letterboxd:
The most 2000’s movie i have ever seen
There are simply to many aspects that does not make sense, the fact that the conclusion is basically that the source code was more complex, and capable of doing more than what they believed it could do - contradicting all their research. It is just such an extremely vague explanation, not thought out at all. The movie is so highly intellectually put together and then it is all thrown away by the ending of the film.
