Quick Synopsis: When the residents of Littlehampton start receiving letters filled with obscenities and hilarious profanity, Rose, a rambunctious Irish immigrant, is accused of the crime.

This is the fourth time I’ve written this introduction. The first time I mainly spoke about how the trailer was misleading and the final film isn’t as hashtag girlboss as you’d think. But I couldn’t go into that any further without spoiling the plot. My second attempt mainly focused on how Olivia Colman is undefinable, how you never know what you’re going to get from her, is it going to be an intense award-winning drama, or something sweary and British? That ran out of steam when I (and this is genuinely true) every path I took led to a punchline where I talked about how I suspect a beloved comedic actor shows hallmarks of being an abusive piece of shit. My third attempt wasn’t a review but was in fact a recipe for tomato soup. That was thrown out because I ran out of croutons.

So how do I discuss this without giving too much away? I can start by pointing out the most important thing; this film is filthy. If you have an elderly relative who is thinking of going because “I loved her in that thing where she played the Queen, she seems such a nice lady”, warn them. I haven’t seen swearing like this since The Thick Of It, and just like TTOI, it’s done beautifully. There is an art to swearing. If it’s done wrong it can come off gratuitous and immature (see, well pretty much any Tarantino movie), but when it’s done well then it can provide sentences with an artistic rhythm which flows beautifully (think of the scene from Planes, Trains, and Automobiles). This is more of the second, with the “shits”, “cumbags” and “piss” flowing like a British river.

The story is one you want to see unfold. The timing of the reveal of the letter writer is perfect. If it was any sooner it wouldn’t feel earned, and if it was later it would feel like the mystery was too small to justify waiting that long. The mystery is possibly the weakest part, there are not enough potential suspects to drive the suspense. But the aftermath of the reveal is very good. It moves into more of a caper, the police trying to prove their suspicions, the suspect proving their innocence, and the guilty party being racked with guilt. It gives everybody involved more to do and is genuinely quite tense because you’re unsure whether the person will get away with it.

None of that would matter if it wasn’t for the performances. Jessie Buckley and Olivia Colman have tremendous chemistry and I’d like to see them do more together; I would legit love a buddy cop movie. Anjana Vasan is a ball of energy and made me really want to see a second series of We Are Lady Parts. Joanna Scanlan is a lot of fun too. I wish some of the background characters had more to do though, there are inklings of personality for a lot of one-shot characters, and I’d have liked to have seen more of them.

Overall, Wicked Little Letters (or WLL, pronounced Woo-lil) doesn’t quite feel big enough to earn a cinema release, but it’s one you will be very glad you watched. Maybe don’t put it on over Christmas with the folks, but watch it when you need to laugh.
