Firstly, the bad points: That is, the one bad point. The art on the boxset/menu screen is obviously not the geniune art is an incredibly lazy imitation. Was it so had to just get a screenshot?
The good points: Completely ignore the above because MOOMIN. This is an incredible series. I loved it as a child, and my partner and I recently thought it wise to purchase the DVD sets. And We were not dissappointed in any way. The characters are just as I remembered them (Snufkin was always a favourite and still is) and wow. It's an engaging program, and it somewhat follows a storyline, not so much that you'd need to have seen all the previous episodes, but it's not just Random Episode followed by Random Episode, like a lot of children's television (and some television meant for adults these days...). And the best thing is, it isn't patronising, so as an adult, it isn't embarrassing to watch. If you enjoyed Moomin in the 90s, you'll still enjoy it, and if you have children, I'd recommend showing them what Mummy/Daddy used to watch, as it's far better than whatever rubbish they're showing these days! [But of course, buy the first volume first!]
