Watched a few other new shows today (not going to type out their JP names, just use a similar abbreviation), and I'll give them all 3 episodes.
reborn demon king(?): Isekai where a kid gets reborn as a demon king in his favorite game; generic, but too soon to tell if its totally bad.
Silent Witch: Could be good, but I really dislike super shy MC's
White Mage gets the boot: This is like the third exact anime I've seen in the past few years. Super OP character gets thrown out of the hero's party. Kinda confused with the backstroy shown in the first episode.
Kaiju 8 + Re-Zero: Super generic MC who likes to fight (even has the over used duo color hair), gets sent into another world where he can transform into a demon type thing, but he can also reset himself if he dies.
Ruri Rocks: Truly is an anime about learning geology. Nice art style.
New Saga: We've seen this theme before. Hero gets sent back in time and has a chance to redo things to save those he lost.
Out of those shows, I am very pessimistic about the Demon King and the Kaiju/Re-Zero shows, but the rest have potential.
