I watched it the other day... I feel there's not a really good balance between humour and seriousness... To be honest, I find the original concept really silly. It would have been better if they were not nazis. That is just over the top. You can't mash up historical things like this with space travel, that is just not a good match. I understood the satire, but I just thought it was not really working out. Special effects were good I suppose... Costumes were really cool too, but that's pretty much it.
