It makes sense in the context of prior established lore, as Darth Sidious was Darth Plagueis' apprentice, and it was established in canon that Plagueis found a way to immortality, and Star Wars quite clearly has viable cloning technology, so bringing back Palpatine makes sense in the setting's established rules. It is still a poor choice as it both shows creative bankruptcy worse than having a second Death Star in Return of the Jedi and it retroactively makes Anakin's sacrifice meaningless.
To be fair to Jar Jar Abrams though, what else could they have done after Rian Johnson killed off the main antagonist in the second movie of a trilogy without any thought as to what to do afterwards? It was a little too late to set up a new villain and Kylo Ren would have made an even poorer one. Alas.
True, and I do not expect everything to be consistent in a show of this length and with that many changes and mysteries added to elongate the series past the point of what the creators wanted to do, just because it was wildly popular. However, most of the problems are the less problematic retroactive continuity changes, like when it was established that the Man in Black cannot kill candidates directly, even though he quite clearly killed Eko when the actor wanted to leave the show, or how he was supposed to only be able to take the shape of dead characters, but often ran around the jungle as Walt before that rule was thought of.
This is in contrast to the issue with the outrigger that should not travel through time with the group. Here the violation follows the establishment of the rule, without any added clarification.
My thoughts on How I Met Your Mother should be somewhere in a thread on this forum already. It is pretty much the only sitcom that I enjoyed, and I particularily also liked the latter seasons where the general consensus was that the show already stopped being funny, but that is on me and my kind of humor. One may or may not like Ted because he is an idiot and the premise of the series was probably not good enough to actually carry nine seasons (the strength of every character who is not Ted on the other hand was more than enough in my opinion), but the quality of the scripts and the work that went into the overall craftsmanship of the series is leaps and bounds ahead of other sitcoms, or most comedy in general. Well, except for the ending.
I cannot comment on Newhart, but "it was all a dream" endings are more often than not just terrible.
You may not enjoy everything, but certainly more than I do, which makes me a little envious, to be completely honest. I cannot for my life fathom how you managed to like Rings of Power, but I admit I am almost curious enough to try Wheel of Time just to see how bad that must be for you to dislike it.
To be fair to religions, they have been around for much longer than the time it took to make the six seasons of Lost, so that is not a very good excuse. I am not sure I would go so far as to say that Lost is an intentional religious allegory in the strictest sense (watch Revolutionary Girl Utena for that, although it not based around Western religion), but it certainly has its roots in the various religions and philosophies of the world and makes heavy use of religious imagery, much like Neon Genesis Evangelion did before. Fun fact, that series also had an ending that was wildly controversial, with a similar problem: offering no narrative closure in lieu of a thematic one. The similarities are striking enough that one might think they were intentional. Most likely not though. Neon Genesis Evangelion was very much allegoric too, albeit on a much more personal level: it was a way for the series director to work through the trials and tribulations of running an almost failing studio and his depression.
Lost, as a whole, can be seen as the clashing of Western and Eastern philosophical and religious thought. The changes on the island, especially regarding the Man in Black / Smoke Monster and his relationship to his brother Jacob can be interpreted as the rise of the duality between good and evil as brought into the larger world by Christianity (also represented also by the commonly played Backgammon, and as Locke said, two players, one light, one dark). It seems strange from our point of view perhaps, but the conflict between good and evil and the inherent duality of the two sides, with the ability to actively chose and even switch the side you are on (through redemption arcs or a gradual fall towards villainy), rose with the prominence of Christianity. Look at the theater plays of ancient Greece, for instance. The ancient Greeks would have most likely laughed at the preposterous idea that Darth Vader would just switch sides at the end of Return of the Jedi as your lot in life is preordained by your destiny - as set by the gods. They would most likely not have batted an eye at Zeus showing up and setting things back to what they were though.
