I don't get the bad reviews. This movie is one of very few movies that made me laugh and chuckle out loud. It's not your typical rom-com movie, it's quirky, and strange in an adorable way. Although at first I thought this movie could have used younger actors, Blunt and Dornan made it work. The Irish scenery is just spectacular, it's in my bucket list of places to see.
Just don't overthink this movie, just enjoy the silliness and quirkiness of the ride. You might want to have closed caption on though (I do with all British movies, or those with Irish, Scottish accents). It's a feel good movie, nuff said. We could all use some these days.
