With that being said, on with the review.
Story: Planetes starts off rather slow. In fact, the "main" story doesn't even really pick up until about episode 10 or so. Before that, you're introduced to character personalities and dreams/motives. This is absolutely necessary though, because without this strong intro, the latter part of the show wouldn't have had nearly the same kind of effect.
Animation: The animiation is pretty well done. CGI is used in quite a few scenes and I didn't notice any problems. My only beef is that I didn't fall in love with the character designs too much. They're good, but I think a few characters got shafted.
Sound: Probably the most lacking area in the series in my opinion. The intro is decent, but hardly anything special. The background music throughout the show is bland and never really stands out. The only music that ever really caught my attention was the ending theme, and it's not wonderful either. I should mention that the Seiyuu's did an excellent job though.
Character: Characters are definitely the biggest plus to Planetes. Hachimaki and Ai are excellent leading characters. The other crew members are nearly equally as interesting as them too. Everyone, like most shows, has their own problems and own ambitions. Planetes does a great job at detailing each character.
Enjoyment: Took me 4 days to complete the show (could have done it sooner if school wasn't taking my time). 26 eps in 4 days usually constitutes hard core enjoyable watching. :) This is a feel good Anime (well, most of it is at least), so what's not to enjoy?
Overall: This needs to become more popular! It deserves better than only a couple hundreds watchers. Take the time and watch it.
