I watched the first episode a few more times, and I've slightly warmed up. It's serviceable; however, any upgrade in my opinion's probably because of memories of "Xenogears". The first episode does too much. It tries to encompass so very much of the "Xenosaga" world that nothing comes off as deep. The different politics and players should be brought out slowly. Instead, we're give small capsules of all the protagonists and antagonists without any real worth assigned to them.
"Here's this guy... He's here, too... This guy's a traitor, but don't tell anyone... Here's someone else for a few seconds... Look, boobies!"
Instead of there being any drama, we're bombarded with meaningless introductions that do nothing to advance the plot. If the story was stripped down with the different tangents left for later, it would have had a lot more full feel. (However, the fanservice with the 14-year-old was unconscionably in bad taste -- poorly animated, too.)
