Unpopular Opinion: "Aquiel" isn't a bad episode. I liked it when I was 13, I still like it now. I'm probably the only person who'll defend the episode, but I appreciate that it puts the spotlight on someone who isn't a model officer who they suspect might be a murderer but it turns out she isn't.
It puts some nice gray into TNG. In another Star Trek series, this wouldn't look like as much of a breakthrough as it does here.
I just watched that last night and no, it's not bad at all. TNG is not my favourite series. I often find it cringe inducing but Aquiel isn't bad.
What a lot of people don't realize (you might) is that Aquiel is TNG doing their own version of the classic noir thriller "Laura". Aquiel is the Laura character, Geordi is the detective taken by her beauty in the painting in her apartment, and the lifeform is the killer that wants to silence her because he shot the wrong person. it was ambitious, but wasn't as well executed as it probably needed to be to pull it off properly.
