The show is getting better but it really needs to address some things.
Who is Subaru?
I don’t recall the show telling me anything other than he’s a gamer from the real world. That’s literally it. I could replace him with some homeless guy and the story would be the same.
If you don't want him to be a blank self-insert, you have to tell me who he is. Say he lost his family in an earthquake and that’s why he cares so much about the people he interacts with in this world. Otherwise he's just another character who heroines love because he's "kind".
How Is This Satire?
Some people have been saying that the author hates LNs and that Re:Zero is supposed to be his deconstruction. But it's not really that good at it.
First, few of these tropes are exclusive to LNs. “Trapped in a fantasy world” and “time loops” can be found from Chronicles of Narnia to Tom Cruise's newest scifi film.
Second, being edgy with your tropes for the sake of shock value is older than Evangelion, and mainstream is becoming edgier anyway.
Third, meta-humor is a big problem with WNs but gets played straight. Most conversations revolve around pointing out how genre-aware the protagonist is about everything, or else it just turns into tsukkomi style pointing everything out.
Why Would Anyone Want To Save These Maids?
Subaru has only known them for nine days, which is barely enough to form an attachment that can survive attempted murder.
The maids have only been horrible to him, and murder is not a reasonable response to a suspicion regarding a vague threat that has yet to be clarified. Killing someone for smelling funny is considered a hate crime in most countries.
Subaru, even with the time loops, has only known for about nine days. There comes a point when you push a man’s goodwill too far and you start to think he’s just mad for continuing to hold on. If the writer killed Emilia instead at least I would have bought Subaru caring for her considering his interactions with her were romantic.
