I had a decent enough time with The Space Museum. It's hardly exceptional - while I find it a pretty fun set-up and an interesting exploration of time travel ideas the series would be exploring for a very long time, and I found the setting fun, too, it does lose steam after a bit. I definitely find part one is a great start while the rest largely flounders and struggles to live up to that, but nothing about the rest of the parts are entirely objectionable, either.
