I'll be honest, I didn't expect much when I dared to watch this film, in fact, from the very first scene I thought "Gosh, this seems like one of those cheesy and nonsense Lifetime movies" (and it's kind of like that), but even though I would not say this is the greatest movie ever, I would neither say it's a terrible one; "10 Things We Should Do Before We Break Up" is an actually interesting movie for a good hour, seriously though, I'm the most impatient person and I didn't feel like "OMG, end up already" since it's in fact a pretty short movie. Talking about a deeper manner, characters are not great though and a lot of people say they're actually unbearable, I might not disagree but at least I'd say they're not perfect but human.
The plot is simple but slow for almost an hour, the final stage of her pregnancy goes very fast and we, as an audience, just feel really cold about it, the finale is just "meh", I'd say is unpredictable because I never thought they would dare to end it just like that like I get the fact they're not meant to be, but there's no catharsis, neither an evolution of the characters. By the end, I was just like, "Really?"
Anyway, I'm giving it a 4 since I liked the first part, only that.
