A wedding should be a couple's best day of their life! This is what drives not only the bride and the groom, not only the wedding planner -- but everybody who is invited (and one who is not invited).

We get to see backstories of the couple and a few of the guests, who all want to make this day special, while they have their own aspirations. I love the aquatic theme that's going on while they tell their own stories -- even though it's never quite clear why it this theme, not another. (If you know, please tell me!)
The film also takes its "Chekhov's Gun" very seriously, but no need to pay extra attention, you'll see when it's used.

These sincere and genuinely nice characters do their all to make the wedding the best wedding of all time -- and overshoot their goal; this is where most of the humour comes from. I waited for things to go wrong horribly. But this is not the kind of comedy, and it works!

There was a bit of sexism in the beginning -- the long-suffering husband(-to-be) who wants to please his partner, and the "guy outing" (what are guys up to when they are alone, hehe... not that funny, all very innocent though) -- but the groom and the ex-boyfriend are so cute and nice that I can forgive them. There was also a story arc with a bit of "diarrhea-is-funny", I don't mind that kind of humour, other viewers might.
A bit disappointing is that the female characters are not only in the minority but also much less interesting then the men (with the exception of the wedding planner).

All of the actors made their characters come to life -- and I fell in love with all of them. Especially notable was the scene where the fathers and old schoolmates entertain the guests, what a choreography!
There are two storylines that happen simultaneously but are shown after one another; I wonder if they couldn't have been shown as they happened or if this would have been too much? I suppose it's the latter, because overall the pacing was excellent, fast scenes and slow scenes followed an easy rhythm, according to the story.

I wasn't bored for a second, I laughed a lot -- and there were a few heartwarming moments. The ensemble plot and the multiple points of view with their backstories show us a wedding that will be memorable for all of them, the couple, the guests, and the staff of the location.
