the op basically sums up how i feel about it. i see the new timeline as objectively good on its own (save for all the forced and misused references to the original timeline), but not really what i would want to replace the original. it just feels completely different, and i get that that's what a reboot is supposed to be, but... not this. it's hard to describe what exactly is wrong, so i leave that to someone else.
regardless of how i feel about it though, given the handheld and console two-pronged move this e3, i'd be very, very surprised if the series deviated at all from its new LoS direction in the next, i dunno, 5-10 years? maybe not that long, but something like that. one can't really argue with the sales of LoS. so your only real option is to get used to what's coming, maybe even embrace it, or ignore it altogether.
