I absolutely didn't mean to suggest that ME2 fans have shallower tastes; I simply mean to say that if you set ME2 as your baseline, it's understandable that the ME1 squad would pale in comparison. I do think that Rule of Cool did play a role in ME2's character design; just in terms of the visual presentation of the characters, this influence seems pretty evident. It's not a bad thing in its own right; not necessarily to my tastes, but I think it is definitely there.
I can agree with that. I'm not necessarily adverse to what you say about the ME1 characters compared to the ME2 characters: For example, I think Kaidan is a strong match, as, at least by ME3, he's one of the best Biotic Soldiers in the alliance military. Garrus is a lot more than a jaded ex-cop; prior to joining C-Sec, he was in Turian Special Forces and was at one point a Spectre Candidate. Tali is mechanical savant when it comes to technology, and your assessment of Wrex was spot on, along with Liara and Ashley, both of whom are people not suited to the mission with Ashley being a standard infantryman with no outstanding skills or experience and Liara being a civilian archaeologist who's actual true relevance is questionable (she can be saved dead last after everything, including Virmire, at which point you know about the Reapers, you have the Cipher, you have Saren's destination, and you have the location for it). But yeah, I see what you're saying. And I don't really feel like they're 'my' team as BW tried to make them out to be. As you said, they're people thrown together by circumstance to solve a problem.
Versus in ME2, the only characters who really don't seem to truly standout are Jacob and Tali again, but even then, they are both competent. Jacob's a solid soldier and competent biotic, and he has done some stuff in the galaxy that's worthy of notice (if you played Galaxy and read the comics where he single-handedly rescues Miranda from a group of Blue Suns Mercenaries), and as I said, Tali is still a savant technician and engineer who's not on the team for her combat ability so much as her technical utility. Otherwise, yeah, you have the genetically and physically perfect Miranda who has a lot of experience as a Super spy/Secret Agent/Field Officer/scientist/leader (by her own admission) and she's a gifted biotic with exceptional (for a human) skills and combat training (albeit private training). You have the genetically perfect Krogan Supersoldier in Grunt. You have Kasumi, the best thief in the galaxy (though to be honest, why you need a thief for a military operation is a bit odd, though it's likely she's wanted for her infiltration and hacking skills), the veteran mercenary and former soldier who has thrived in the galaxy's criminal underbelly in Zaeed, the most powerful human biotic to ever live who is also a deadly, psychopathic career criminal who loves mayhem in Jack, the genius polymath scientist who is a truly gifted geneticist and biologist who also happens to have a past as an STG operative in Mordin, a centuries old Asari warrior who has dedicated her life to punishing the wicked by the ancient laws of the Asari and has spent centuries honing her martial, biotic, and combat abilities to do such with Samara, a master assassin and infiltrator with competent biotic abilities in Thane, a Geth platform that is one of the most advanced and sophisticated platforms ever created by the Geth, and Garrus, who has definitely spent the last two years honing his skills and leadership abilities. I see where you come from there in comparison to the ME1 crew, and I wholeheartedly stick with the ME2 crew since you do work to gain each member of the crews' undying loyalty.
Then come ME3, it's implied that the people thrown together by circumstance are your true companions over the ones you worked your ass off to gain as loyal. I simply found that unconvincing and asinine.
