[Question] Opinions about Cameron Monaghan's acting

I've been a fan of Monaghan's work in Gotham and Shameless, but I don't usually analyze an actor's performance unless their scenes felt off, especially when the characters he played - Ian Gallagher, Jerome/Jeremiah Valeska, just resonate so well with me. However, it's been bugging me recently about how others view Monaghan's acting in Shameless. Some like to say that Noel Fisher carried many of Gallavich scenes, yet I don't really adore Mickey like a lot of fans do. So, here are the few things brought up once in a while:

1. Cameron's accent. I'm insensitive to different regional American accents so I couldn't tell them apart, so can someone explain to me how different from other Gallaghers, or how inconsistent was his accent throughout the show. I know for certain he's not using his natural accent, and he did have obvious slip in S9 "Black-haired Ginger" where he sounded entirely like Jeremiah during his hearing. Would be great if someone can pinpoint the accents or whatever in-between he used.

2. Cameron's delivery. Some pointed out his deliveries were, albeit good, but not great compared to Jeremy or Emmy. I would like to hear someone elaborate from what perspective it threw you off. Some pin it on writing but I would love to keep the complaints regarding the writing aside for now.

3. Cameron's telegraph. I have minimal knowledge of acting techniques so I would love an elaboration on what choices you think Cameron made that felt oddly telegraphed. Would love a comparison to understand how it could have been better.

If there are other aspects worth bringing to light, don't hesitate. I adore Monaghan's work, that's why I'm interested in knowing more on the professional side of reviewing his performance. So, by no means are these intended to badmouth Monaghan, but rather to analyze his performance and better understand what others felt he could have done differently to improve his scenes. Regardless if you're a professional in the filming or acting field, or just another enthusiastic audience like me, feel free to share your thoughts.
