Numerous chuckles abound, but overall its just a little too clever-clever/pleased with itself, dragged a bit for a 92 minute film.
The dumbest film I've seen in a while. I didn't hate it though, just. The plot, what there is of it, doesn't make sense. Ignore that and it's near watchable/OK. Margot Robbie is easily the best thing about it - the film could have been terrible without her.
Jared Leto's screen time is thankfully brief.
This review may contain spoilers. I can handle the truth.
Hysterically dreadful, full of unintended laughs - the pretentious Nietzsche quote at the start, very unscientific notes in scientific journals ("DARWIN WAS WRONG!"), the terrible philosophising ("You have to empty your bucket before you can refill it!"), the numerous close-ups of a copy of Dante's Inferno before and after it is burned in a fire (geddit?). But ultimately, it's got a plot that doesn't stand up to even the smallest logical scrutiny. 2018 may have its "worst of the year" already sown up.
