He won an award for it recently and I was thinking, has he actually won it for the this? Or is it for the general character of Gus Fring? Cos he’s just kind of in this. Existing… for 3 seasons…
As you rightly point out, Mike is basically just repeating his arc over and over again - as is essentially Jimmy/Saul - but at least it is an arc, and you could quite plausibly say that Walt and Jesse repeated the same basic learning curves several times throughout BB…. And they did at least have a beginning and end. Gus has a beginning and end too, but they’re ALSO both in BB! So he’s just…. There, in this. Being kind of cool.
And anyone who says the little scene we got of him reflecting over a glass of wine and a brief bit of flirting is a better bit of character drama that teaches us more about him than seeing him meet the cartel, watch his lover die, and then risk his life for an immaculately plotted revenge against them all, years in the making, all in one episode is - let’s be honest - a massive lying ponce.
Esposito won the Hollywood critic association award which were a bit of charity if you ask me given BCS itself "tied" with succession for drama award for "cable" shows whilst they had different categories for broadcast and streaming. Still I agree that it was a bit preposterous to award him for BCS, he should have won the Emmy for supporting actor for BB S4 ahead of Paul.
Characters unable to let go of their defining traits is a trope established since the days of Sopranos. I don't have an issue with it. Walt's inability to suppress his pride and and desire of being grandiose drove the plot of Breaking Bad. They key here is that BB burnt through a lot of plot despite making for room for episodes like "Fly and "Five days out", which were character studies mostly. After a while I tire out of shows like Mad Men which just keep hitting the same theme without any meaningful plot progress (after S5 specifically in case of Mad Men). I don't think Mike's storyline in BCS had any meaning after S3. We knew where he would end up at the start of BB and knew his back story. Everything else in between was just fan service of showing him use his Batman like skills to navigate one situation after another. I don't even have a take on Fring's story in BCS, if anything watching BCS before BB, takes away some of the subtlety and surprises the character throws up in BB. For example his scene of gutting his man in Box Cutter (S4 premier of BB) would not be as chilling after you watch him in BCS.
