I too think it was kind of abrupt. Also,
- Too much focus on humans, I came to watch freaks of nature clash for at least an hour of the film, not 15 minutes.
- The repeated use of toddlers noticing all the big events put me off a little. I don't know why but it just did, I guess it was ... cliche in a way?
- The main asian scientist had the corniest, cringe worthy lines ever.
