I some what agree with this. Though, it didn't create as much of a problem with the series for me. On a psychological level, I find it completely acceptable for people to make vastly overbearing and unnaturally strong emotional links to other people, in states of heightened stress/emotional and psychological trauma. Subaru attaches himself to Emilia in a way she doesn't even expect or understand herself. This is made vastly clear during their brief conversation after he makes an idiot of himself during the ceremony and afterwards: His love is a one way street, due to shared experiences that she has no knowledge of. The show makes it clear that he's spent basically about a month with her, though to her it's only a couple of days, because of the short cuts he takes in concluding the problems he's come to understand and resolve.
Subaru is a loner at heart and doesn't appear to have had much contact, or any relations with girls prior. What he has, is more likely a form of emotional hunger, rather than a genuinely true love. Hell, he has to admit himself, that everything he has done has actually been for his own well being in truth. Emilia is more a focal point for his desire to have a satisfying life. Don't forget, that he does shift his attention to Rem at a desperate moment, being fully willing to go and live with her. These are child-like emotions of an unstable mind at work. He may insist that he loves Emilia /after/ Rem turns him down, but it's clear that he's just seeking comfort in someone, if not anyone and Emilia just happens to be the first choice. I genuinely believe she could have been anyone. However, in her, he has given himself a cause and purpose and he's willing to do everything he can to make that delusion a reality.
As to why he acts like this, Emilia is literally his saviour. In their first encounter, she protects him, helps heal him and stays with him for a needlessly long time, to her own detriment. Subaru is instantly attracted to these elements of her personality, more than likely because it's the first time anyone's shown him any real comfort or kindness. Through death, he's become more desperate and borderline feral. He's learnt of pain that he could never have experience or known before and wants to run away from that as best as he can.
I agree that Subaru is an obnoxious character, on numerous levels. Although, I enjoy watching characters like his interact with other people. Especially when there are negative consequences involved. I just find them fascinating. The worse the character and the more despicable their interactions, the more loathsome the personality, the more my morbid curiosity desires to see them pay and learn, or suffer.Beyond my criticisms of Subaru's construction that he was just really...really...really obnoxious. Sometimes it is good that a series is painful to watch because it is eliciting pathos, but others it just means that your character is an ungrateful, immature, self-deluded teenager who is irritating as hell. We've been over it time and time again in this thread, but I still don't believe that it was necessary to have it be as unpleasant as it was. Having a character be unpleasant and having the experience be unpleasant are two separate things.
He was presented differently, in a more intelligent and thoughtful manner, though not earth-shatteringly so in the Light Novel version; However, that's not worth factoring in, as the anime presentation of the character is its own thing.
In truth, the series has acted like a very prolonged introduction and its cut off point has ended up being rather awkward. This is one of the few times, where I've actually thought they could have cut a lot of parts, to tighten up the overall delivery of the show. They've been extremely thorough with their coverage of the source material, but it wasn't this necessary, in my opinion.Finally, I still have a more personal complaint that I simply disliked much of the focus of the series. I was most fascinated by the royal selection, the backgrounds of Emilia and Roswaal, and the connection the Witch had to the past and present. In 25 episodes our knowledge of these aspects hardly grew. Aside from a single tantalizing comment from Roswaal that he was interested in destroying the Dragon, and the implied centrality of Emilia winning the election to achieve this goal, our knowledge was not advanced. When the series devoted much of its time and effort to the white whale, Wilhelm and new characters, etc. I lost interest at the crucial climax, leaving me to simply finish the series by way of habit.
Absolutely disgusting. How dare you have an opinion. I will give it a 7/10. It had some heady highs for me, but overall, it was just a solidly entertaining series.In the end I'd rate it a fair 6/10 which has a few arcs that are quite engrossing but otherwise is hurt too much by unsubstantiated and irritating characters and pacing/focus.
