Un dolor real

I won't cover what others have already said. This isn't a comedy or a road movie and it's not some commentary on the horrors of war.

For me this quaint indie (feeling) flick is really an observation about living with someone with mental illness. If looked upon from this angle it is well observed and touching and uses its three acts to unfold all the different dynamics in the cousins relationships using the backdrop of the road trip and the visit to the concentration camp. It deliberately subverts expectations by not providing a defined ending (often the case in this situation) and the scenes often don't lead to expected outcomes. That's what life can be like when your are dealing with that issue.

For me this made the film an interesting (if flawed) study that was definitely worth the watch. YMMV.
