Apparently those against Tali in general (to use a diplomatic term) think that liking the loyalty mission is just a generic response to liking the character. Ever get slightly creative and try to understand that we like the character
because the loyalty mission is good? >_> It's certainly one of my reasons, among many others.
As for the mission itself, it's got most of the characteristics that really drive the best moments of the game. There is significant backstory about a race that was otherwise left in the dust in ME1. It also involves plenty of backstory on the character specifically, as there should be in any given loyalty mission, considering what you're there to do. There are multiple outcomes for Paragon, Renegade, and Neutral dialogue. Also plenty of optional dialogue, which even comes back to affect later dialogue. Some of the decisions made in the conversations may come back to have an effect in ME3, as well--Even if you complete the mission perfectly, you can still give different recommendations.
The mission's structure is well-designed, as well; it opens up with a fun conversation, then has you move on to a combat area for variety (but you still have the choice to stay and go into more dialogue for a while, if you want backstory and different speeches). Even during the combat area, there are some well-placed breaks for additional dialogue encounters. (This is something that makes Mordin's loyalty mission nearly as good.) Finally, you return for a climactic finish in the courtroom. Legion's influences here are enjoyable. And to top it off, the
music is comparatively fitting and supportive, with some nice situational shifts.
Do whatever you want with your toy ships. But leave my crew out of your political bullsh*t.
