We watched 3 more episodes last night, and she definitely seemed to like them more. I know I was starting to enjoy it more too.
She seemed to have a better time, so I think maybe she will hang in there with it. I think what helped is it had a lot more locations/situations than the previous episodes, and the scenes were not nearly as long in most cases..
I don't quite understand the Lucky Channel bit, it seems very hit and miss with its jokes to me, but its at the end of the episodes anyway so its not like you can't skip it.
re: PlanetES I have gone back and forth over it in the store before. I think my dad would probably watch it.
I have no intention of ever watching School Days, just based on the talk I've seen about it. Much less showing it to my parents, but I doubt it'd make them think any different of me. I'm already really screwed up as it is

I've watched some Code Geass on and off (waiting for OZC to finish R2) and my mom will kinda pay attention to it, but usually just sits there eating dinner or reading a book, and will ocassionally watch. She seemed more into Glass Fleet though (first time she ever asked me if I was gonna finish watching something) so throwing some dark stuff at her would be OK.
In that vein, I have considered Death Note. It liked it when I watched it on TV and I know I missed some important stuff here and there. I was also thinking she would really like Blood+, because it is a good mix of action, story, and romance. And does have a sort of "old world" look to it in a lot of the flash backs and later locations. I've been waiting forever for a Dual Audio high quality release to be put up.
Thanks for the other new suggestions too, I have quite a bit to look up..
I've also been thinking about something like RomeoXJuliet, I know the basic premise from Anime Insider's cover story (R.I.P) but not sure what its supposed to be like overall or if there are dubs available yet/planned.
But maybe that's something she might like.. I know she likes action stuff, we watched nearly every episodes of Battlestar Galactica when it ran on Sci-Fi (the new one of course)
