Should have been called "Crush Actually"
There was no deep and developing connection in any of the love matches. They're mostly either love at first sight or crushes from afar.
The Colin Firth/Sienna Guillory match did demonstrate a love that grew, but they could barely communicate at the time (he said in the restaurant that he hardly knew her).
The Martin Freeman/Joanna Page match wasn't shown beyond the shallow grabs at work.
The Gregor Fisher/Bill Nighy business bromance probably came closest.
But I did laugh at the octopus in the car.
