On the upside it's free, and that whilst you aren't permitted to take any photos, there's actually nothing to take photos of. I'm also glad I went, but it's definitely the least interesting Jewish museum I've ever visited.
On the downside it's not an interactive museum (which you'd expect from something completed recently), with just a handful of photos and otherwise just literature and one (fairly good) film. This would be dull for children, and even as an adult I started to find it a little tedious towards the end, and was disappointed with the lack of firm facts or background contexts, but rather the history being told more through anecdotal facts.
Also, the whole interior looks like a conference centre.
