I think the problem is the writers
I never EVER like how they made Sentinel so nonchalant towards Blackarachnia
You telling me the same bot who would get terrified by a kitty yet CALMY tells BA to kill herself
If you ask me, I feel like this was a rather plot device than expanding Sentinel's complex writing
Listen, we know oplita/oparachnia is Canon
So I realize they're going the fuckass girl realizes her popular jock boyfriend is a jerk and realizes the unpopular need guy is a nice guy trope. So yeah, I firmly believe this was to push the oplita agenda than focusing how this interaction will impact Sentinel and Blackarachnia
I'm not surprised Sentinel told BA to kill herself, my problem is that he was SO calm about interacting with her
He should have been more dramatic, like Sentinel drastically change because of her after Archa 7 and you're telling this is it?! He should have crash out immediately
And maybe I sound insane but I often feel like the writers aren't sure if they're making him an interesting complex character or a just pure asshole to make Optimus look good (Sentinel is the foil to Optimus but I am disappointed the writers just make it so simple and not more deeper such as Sentinel and Optimus perception to the protection of Cybetronian)
I often theorize Sentinel's character is soooo complicated because the writers aren't either interested much in Sentinel and just need him for the plot to move on
Listen, I love Optimus but I hate Sentinel is constantly used as a example to make the audience see "Hey! Look Sentinel did a bad decision! Notice how Optimus didn't make that decision? Isn't Optimus great?"
Like nothing wrong but it is so obvious, it has become irritating. I prefer Optimus to make mistakes and become better by not needing Sentinel to fail so he can look good
It could have been really great depth to both of their characters where Optimus and Sentinel had valid points like whether Megatron deserves to live or not
It could have been very interesting that for once Optimus was wrong and Sentinel was right about a certain situation like maybe Starscream wanting to redeem but in the end betrays the autobots but Sentinel manage to stop Starscream before the seeker could harm Optimus
Like give me more than just "Jerk Sentinel making Optimus look good"
I remember a Tumblr blogger was complaining where apparently Bulkhead stated Wasp was cruel or something like that in the tfa series and I was baffled cause deadass are we seriously having Wasp be compared to war criminals which even the Tumblr bloggers agree to my comment
