Odds and ends. I've seen a lot of this stuff, so I'll throw out some comments.
Area 88 - saw the first two episodes a long time ago. It looked good, although I never had a chance to see the remaining episodes. Anyone remember the video game UN Squadron? My guess is that in Japan, that game was entitled Area 88...
Tenchi animation - there are three different Tenchi series, and three different Tenchi movies. Each of them has their own style of animation, and I've heard that Tenchi in Tokyo/ Shin Tenchi Muyo (English and Japanese names respectively), which is the last TV series, and also the only one I haven't seen any of, is the worst looking visually. The third Tenchi movie, Tenchi Forever/ Tenchi Muyo in Love 2, also has a distinct art style. The plot isn't very Tenchish, either, and many fans strongly dislike it. The animation style in the first TV series is similar to that of the OVA, but of lower quality (as is typical with TV series and OVA series).
BGC 2032 vs. BGC 2040 - Who would you rather listen to - a band called Seikira, or a band called The Replicants?
Any Blade Runner fan will know how to answer that one.
Seriously, the original BGC was an OVA that kept getting extended (The series ends with episode 8. 5 new episodes had been approved, but one of the two companies creating the series went bankrupt before the new episodes were made). What that means is that while the overall series does not have a clear cut plot running throughout the episodes, there are elements of a story that crop up.
BGC 2040 has a number of similarities, and the same names on many of the characters, but there are a lot of differences, as well. I haven't seen all of the series (I think the last episode I saw was 14), but here are a few of the non-spoilerish items.
Dr. Stingray is not a sinister figure in BGC 2032. Mackie has lived his entire life with Sylia, and is normal in every way (Sylia may not be, but that question is never answered). There is no butler in the Stingray residence. Sylia runs a lingerie shop, not a clothing store. Boomers don't mutate when they go nuts. Its hinted that the AD Police can deal with normal boomers that go nuts (although we never see any). Combat boomers are still problematic for the regular troops and firebees, though. K-Suits are actually useful in 2032, and a couple of older police K-Suits manage to take down a military boomer in one episode (at the cost of both K-Suits and pilots, though). Leon doesn't hate the Knight Sabers, nor do the AD Police. Leon has his trademark shades and a REALLY big pistol. Daley is gay, and jokes about it with Leon all the time. Mason doesn't have the boomer fetish that he has in 2040, and doesn't overtly plot against Quincy (you never see it on-screen). Boomers are much more intelligent, and can be camoflaged to look like humans.
And finally, in 2040, they emasculated Quincy. 2032 Quincy would have had that guy as an appetizer.
