Unpopular opinions

Best part was Morinth's apartment when you investigate the various items.

Krogan statue.

Sword.

Chess set.

Man she's evil.

don't know what my favorite loyalty mission was since I may change my mind tomorrow.

I like the renegade interrupt on Lawson's mission and really enjoyed watching her throw the asari across the screen
deciding the fate of Taylor's father was good. Depending on which one is chosen, the squadmate will make a comment. I also like what Jacob has to say to his father about what happened
it was nice having Shepard dressed up for Goto's mission. Still surprised Hock didn't make any attempt to apprehend Goto if he had an idea it was her. Her flying leap to the gunship was.....sure why not? If she was able to disable the shield, why not go the whole way by shutting down the gunship?
I like Zaeed saying "fry you SOB". Unfortunately the workers have to die.
Thanes was alright. Being able to shoot the character that little Krios was suppose to kill. I did like the interrogation. In and out in less than 30 seconds.
Tali's loyalty mission seemed to be backwards. Meaning that I get renegade points for handing over the information about her father to the admirals and I get paragon points for not. I didn't agree with that.
the interrupt during Mordin's mission while watching the krogan burn was alright.Watching Mordin shoot maelon. Nice.
the rest I found boring

I found Conrad Verner's appearances in ME2 and 3 to be not only unfunny but an utter waste of programming, especially since his appearance in ME1 wasn't meant to be a gag in the first place, but a display of one of the negatives of fame.

While i didn't care much about this interaction, it's a shame that Bioware/EA couldn't be arsed to fix the Paragon import of it not importing properly, despite the fact that it was fixed in a fan patch.

I rather have Bailey show up at the car lot instead of the asari

If I was Wrex, I would never have confronted Shepard about the genophage being sabotaged. I would've waited until after the reapers are dealt with.

I wanted my Shepard to tell folks it was Liara that knew what happened to Shepard's corpse

The moment where Mass Effect's main story was doomed to collapse was when Shepard began hunting Geth for no reason post-ME1.

(Although arguably it was when the Reapers were revealed)

And when Shepard actually does ask a question, s/he always sounds really dumb (especially MShep).

Garrus is better than Tali for Tech in ME1.
(Because he has Adrenaline Burst)

I understand you aren't Liara's biggest fan.

Badass may not be the right word or whatever, but generally it means toughness (not necessarily physical, sometimes inner or strength of will) being uncompromising and intimidating. 

Liara isnt necessarily the latter, but she quite easily develops parts of these traits from ME1 to ME2.  
In Redemption, she is unsurprisingly, still dependent on others (in this case Feron), but unwilling to be dissuaded in her dogged pursuit of finding Shepard (she also deals with the turians and Batarian who were preventing her from leaving the ship in what one could argue as a badass manner).

At the end of Redemption, Feron by her own actions is kidnapped, but Shepard's body is safe. A badass can make a mistake, and unlike keeping the recovery of Shepard's body a secret, she does spend the next two years trying to find Feron to undo her error.

Even if not to Shepard, in her new information broking role, she would have to be tough, uncompromising and intimidating in order to be a success (even if Ali Hillis completely fails to carry that across when we first meet her in ME2).

Lair of the Shadow Broker, Liara chases down Vasir, pushes aside goons, and helps Shepard take down the Shadow Broker by working together, while the other squaddie naps under some rubble. 

In Homeworlds, she holds her own against the Illusive Man, surviving his attempts on her life. And saving another drell's life. And in ME3, she is the only survivor at the Mars Archives, and we met her in peril, but hardly in need of saving, showing how capable she has become. She's also still the Shadow Broker, meaning she must still be pretty good at coming across as intimidating and uncompromising at least not when Shep's around.

i will grant you that there are plenty of face palm moments in ME3 when it comes to Liara, especially on Thessia, but that is as much fault as the writing of Kai Leng as it is Liara.

to deny various examples that show Liara's development and capability, and times where it is quite arguable she is a badass, isn't so much an unpopular opinion, rather just choosing to ignore attributable positives of the character because of ones overwhelming dislike for the character.

I'm not going to argue this further since your bias towards Liara is so glaring, bordering on petty. 

I am not disparaging the dislike of the character. You can dislike Liara's character all you want. But to just dismiss any and all cases of Liara's development, and twist things so that  they  back up your biased and negative view of her is just very one sided. I would not want to be someone on here knocking Traynor, I couldn't imagine the response.
