I don't know how much point there is to align bands along a love/hate axis.
I am old enough now that i just see bands phase in, and phase out. DT phased in in the 90s where they almost couldn't do wrong. Even their "duds" ( e.g. FII) later ended up in their top 10. But, just like every band in existence, there is a time when they are hot, and a time when they are not. Rush's heyday was in the late 70s and early 80s. DT's heyday was in the 90s. To me Steven Wilson is hot right now, and I'm sure in 10 years I will look at today and say "the good old days when Steven was on. Too bad his new stuff doesn't do it for me".
I don't know. DT try for sure, and I applaud them for that absolutely. But to me they simply joined the long list of bands that I regard highly as a band of great past, but whose late output is lacking. These guys are in their 50s, and as somebody said earlier, DT are in the "home stretch". Nothing wrong with that, but I also don't really expect magical things anymore. Only precious few artists managed to stay relevant over decades, and they did so by entirely reinventing themselves. DT, for better or for worse, stuck to what they do with reasonably little variation, and there's only so many times you can tread the same ground before you are repeating yourself.
Another aspect of this, somewhat related to this "reinvention" thing is, I remember reading an interview with Mikael Akerfeldt around the time Opeth massively switched style. One of his comments was "you know, I'm 40 now, and I don't want to continue doing death metal. Because you know, it's just not believable at this point."
In the same vein, when I see the clearly dyed hair and the "grimy biker" look DT has these days, I secretly wish they moved on from that and reinvented themselves into something ... for lack of a better term, "age appropriate". James can't sing these crazy-high notes anymore, and yes, JP's playing isn't as fluid as it used to be either. They're already overdubbing a lot of stuff these days, and the number of backing tracks keeps increasing, and I really wouldn't want to see them drift into ever more and more constructed, sterile versions of themselves to keep up the façade. To say it succinctly, it would be a shame if DT becomes a Joan Rivers of prog metal. Especially when there's so many interesting musical directions they could take that would allow a more "honest" approach.
