Sappy choice? Yes. Good choice? Definitely.
Even though I have a reputation to maintain, I'll go ahead and admit it: Love Actually is a great movie. Made not of one plot but of several, movies like this normally fall apart; if one story isn't watchable, they all falter. Even worse, if they try to merge the plots too much, it becomes quickly muddled and confused. In this case though, each plot has a great blend of actor talent and script quality. Also, the plots don't intertwine much beyond the people involved knowing each other. There's no merging/diverging of plots, allowing each to stick to it's own and grow as it should without confusion.
It pulls off what it sets out to do masterfully, meanwhile those of us who don't care about analyzing it (normally myself included) will find it to be a superb film. It earns an 8 out of 10 in my book.
