When you're so invested it's always gonna disappoint.
It's the curse of being so into something. You over analyse and feel things that happen so deeply so much that you'll never be satisfied. Plot holes are normal in writing, not everything will be "believable". You can be so invested it's just sucking your joy out of it. This has happened to me many times but I'm refusing it this time! I love seeing the theories and memes though.
The average viewer isn't going to notice so much and those are the ones who end up enjoying it the most and be satisfied with the end imo.
