Probably the most similar to the three you mentioned, it's a film set Swansea in Wales. It's very funny and very sweet without being sentimental. It's about a kid who is trying to balance his first relationship out with the fact that his parents are looking like they're going to break up. It's a film that shot into my favourites so it comes highly recommended.
If you liked Brendan Gleeson from Grand Seduction, then this is a must see. Pitch black comedy about a Priest in an isolated town in Ireland who is threatened with being murdered within a week has to find out who the culprit is and what he must do about it, whilst also tending to the rest of the towns lost souls. I won't say it's particularly uplifting, but I laughed a lot and even had a few tears at the end, worth mentioning if you like this it'll be worth watching
In Bruges and
The Guard as well, both are not quite as affecting, but they are funnier and equally well made and worth watching. Currently my favourite film of the year behind Boyhood.
Very odd comedy that's also set in Ireland that is also one of my favourites this year, about a failing song writer, played by Domhall Gleeson from About Time, who gets the opportunity to help play bass for a band helmed by the enigmatic Frank. As he begins to learn about the messed up band members, he begins to further exploit them. It's very funny and I can guarantee that you'll see nothing else really like it, and it has a really phenomenal ending.
