What were missed opportunities on your favorite shows?

Oh man am I excited for this prompt. I definitely had a long rant about Game of Thrones last night so this list may be a little GoT heavy.

1. Having Lyanna Mormont fight the wight of her mother. We spent a little bit of time with her mother and definitely dedicated footage to seeing her mother specifically be raised as a wight. I thought that the Battle of Winterfell would include at least a few instances of the classic zombie movie trope of having to fight an undead loved one. I thought this could be a great and fascinating moment for Lyanna to see how she would handle this. Now, don't get me wrong, I'm not mad that Lyanna killed an undead giant. But why couldn't we also have seen her kill her undead mother?
2. The Lady Stoneheart plot line. In the Game of Thrones books, Cat is brought back to life, but comes back a little twisted. She is obsessed with revenge and even kills Brienne (don't worry, she's most likely been brought back). This is a fascinating plot line for Cat and it also creates a looming danger as well as the possibility of an incredibly bittersweet reunion.
3. The Starks being wargs. In the books, we know for sure that Bran is a warg (like on the show) and it's insanely implied that Jon is too (although he hasn't really figured out how it works). We also have implied that Rickon has some kind of magic. It's not a far stretch to assume the other Stark children are wargs as well. But no...we don't do this and we definitely just give up on Bran doing useful warging after a while.
4. Bran warging a dragon. I was so hopeful for this in so many ways. The worst mistake was when, in the final episode, Bran says that maybe he can find Drogon. I was like, "Oh yes, here we go. So many problems in this episode but we're finally gonna see Bran warg a dragon." But no...he just gets wheeled off screen. What were the writers doing with this moment? Why even bother including this moment?
5. Garcia and Morgan getting together. I've been on a Criminal Minds kick lately and I just want Morgan and Garcia to be together. I love their dynamic and just want them to kiss. But he left the show...but maybe one day it will happen. At least there is always fanfic.
6. The Inara is dying plot line on Firefly. The writers think that they dropped hints, but they're really only hints if you knew what to look for. I think this ended up being wasted hints because the show got cancelled, but still. Inara's choice of leaving the core planets was always mysterious and it would have been interested to get at why she did. I wasn't a huge plan of the idea of having her be dying, but having any reason presented was better than the clearly BS reason she gave the Alliance.
7. Exploring the original roots of zombie lore in The Walking Dead. Zombie lore has its origins in racism. I am probably misremembering this a little bit, so please take this with a grain of salt. If I recall, however, the zombie lore was connected with slave owners' fears of slaves flipping the tables. In many stories zombies were slaves and they became so by ingesting some kind of potion/poison. Because slaves were the ones preparing food, poisoning was a fear of some slave owners. They especially feared the script being flipped and having their slaves enslave them. The Walking Dead is set in the south where these ideas would have been especially prominent. I thought that setting a zombie series in the south would be used as an opportunity to get back to the original lore as opposed to the more science-y kind of zombies we see nowadays. But, at least as far as I watched, this was just passed over.

Okay I know I definitely have more, but these are the ones that first came to my mind. Please tell me which ones you can think of as I will never not be up for talking about TV shows I love and how they could have been better. Things can be as small as "Why couldn't we just get the Targaryen actors purple contacts right quick?" (yes, this is something that has annoyed me) to bigger problems like "Why can't Criminal Minds do just a bit of a better showing how profiling is used and just skip over the whole clearly fake magic of the cognitive interview? It would make it more believable and accurate."
