That's a bit of a process. Once the other Guardians show up, you'll very often have a lot of transformations on screen just to pad runtime out - showing the full team transform even if only one of them actually does something, Sailor Moon R being the worst offender, I guess. Then the seasons progress and eventually you'll end up missing the full team transformations and kind of enjoy seeing whem when they come up in a special.
It's like with the attack scenes. They're nice at first, but... endlessly repeated. Overall that's a minor issue and it never bothered me, but I can understand when people complain about it. The budget of the show was what it was, and stock footage is a decent way to stretch runtime.
If you like the Tarot card stuff you can also eventually look at how much Astrology hokum there is in Sailor Moon.
There are some things that these early episodes have that will eventually phase out. In a way, the show progresses in certain chunks. There's the first 13 episodes with a lot of little things that quietly get dropped, then everything up to episode 24, then everything leading up to the final Guardian showing up, then the final stretch of season one plus the filler arc of R, the rest of R, then there's S which is... widely considered to be the single best season of Sailor Moon, then there's the season none of us want to ever talk about again (but will, for your sake, if you stick with it that long) and finally Sailor Stars, which was mildly divisive*.
Yeah.
*On the board here. In the larger fandom that season sees a split between love and hate, with very little in between.
edit:
@Bartimaeus I don't get people who say crystal's reboot animation is so pretty. There's a pretty decent showcase in the Netflix trailer.
@LittleArmadillo0 minor spoiler for a later Guardian... it's pretty safe to click and all, but still.
