I really wanted to like this place a lot more. I'm well versed on WWII which is maybe why this museum left me wanting a lot more. There are lots of pictures and writing on the walls as well as old film footage being shown on small screens - very few of which I haven't seen before. I left without learning anything new. The thing that is really missing is that there isn't much "stuff" here.
There are a lot of museums in the area that I liked more such as the Museum of the battle of Normandy in Bayeaux which has a lot of equipment in a hands on atmosphere. If you don't know your history well, you will probably agree with the other 5 star reviews.
