L-bas (2005) was my introduction to Akerman, and a great experience. I remember sitting in the theater at the Berlinale and being completely engrossed by it, sucked into her world. It is a very personal and autobiographical film (but I suppose so are many of her works). 
But many fellow viewers were bored or couldn't make much sense of it. It's a quite demanding film, but if you are able to get into it, a rewarding one.
I think the long takes and philosophical thoughts will be to your liking.
