Okay. As a trailer, the ComicCon "Rings of Power" trailer is good - up to now the series has looked like Fantasy Lands of Generica, which hasn't really appealed. Now the show looks somewhat of a piece with the LotR films, which is a good thing. The "House of the Dragon" trailers have all been okay, I guess.
But I'm always extremely wary of trailers - "The Phantom Menace" had an excellent first trailer, and we know how that turned out.
In terms of the products themselves, again I'm looking forward to RoP much more than HotD - after the last few seasons of GoT, another series by the same team doesn't fill me with confidence. I'll probably end up watching both, though.
In all cases, the D&D movie, and trailer thereof, doesn't deserve to be mentioned in the same breath as the others. The target for that one is "doesn't suck".
