well, after now having watched all of the OVAs (except 8 of course),
1: was alright, but because this was the second I saw (watched 9 first a while ago), I was wondering if all the ovas were gonna use the "and it was all a dream" excuse, thankfully they didn't.
2: I liked it. And why does it seem like whenever Shiratori's around, the wine always gets sabotaged?
3: Not all that fabulous. Also I'm sad that the missing kid didn't look like Conan.
4: I liked it, but as miakakiri said, was really lacking in Conan. And I'd also like to see how Kid pulled the "put all the cups on the table quickly without anyone noticing" trick, he'd have to be movin light speed for that.
5: good times. It's too bad Mouri isn't more competent, or he might be my favorite detective in the series. :V
6: was alright, but the title was a bit misleading. I mean, "vs Kid" implies that he has more of a part than flying around doing nothing, and then doing 5 seconds worth of actual stuff.
7: as a whole, not that awesome. But this part was:
9: good times, but sorta depressing. And given that he was able to deduce that OVA 1 was a dream, I'm surprised he wasn't able to deduce that this was also and that he was not, in fact, sitting on the toilet for 10 years.
