I could pretty much well see why in the recent Toyotaro interview that the Super manga will eventually go ahead of the Toei Anime - it's because of episodes like this that tends to just stretch the narrative as long as possible, with little proggression (or what I would call the "Naruto Effect"). To be clear, Toriyama had nothing to do with this other than outlining point A to point B, with Toei and Toyotaro filling the details in between. Toei just decides to pull the Naruto Effect because of money.
And unless I'm mistaken, even though the final arc of Naruto Shippuden is over, it's STILL ongoing with either in an extremely slow pace, or filling it with more fillers. And yet it's still a hit show. Toei is simply capitalizing on this and may already done so with One Piece (I don't watch it, so I wouldn't know. But I would think One Piece follows the Naruto Effect just as well).
Case in point, Zamasu charging towards Bulma's Capsule Warehouse at the 9:10 mark, finally arriving at the 13:59 mark. So it took Zamasu a near 5-minutes to get to Bulma's warehouse! I dunno what's worse - that or the time Gotenks took a full 30-minutes to get to the battlefied where Frieza and Tagoma are in the RoF arc, when he is totally capable of going around the world several times in mere seconds.
I'm still waiting for the eventual doujinshi of Bulma getting NTR'ed by Zamasu and ditching Vegeta. To be frank, I'm seeing more fanarts of present Bulma and Mai due to their very likable designs.
The Toei writers seem to have a misunderstanding of how anger works with regards to power (or likely never even heard of The Incredible Hulk). So Goku Black's definition of anger and how he used it to further increase his power doesn't appear so convincing. Furthermore, the Toei writers missed an opportunity to make Goku Black more intimidating from his Energy Scythe. Instead of being capable of cutting through Time, Space, and Dimension, it just creates an opening of dark energy that allows him to summon fake Goku Blacks. And THAT was the pinnacle of Black's power.
If you're mad enough to destroy multiple planets and beyond in Dragon Ball, that's normal. But if you're mad, STRONGER than Goku or Vegeta, and the only thing you did at full power was to summon fake versions of yourself.....WTF, Toei?!
It was clear Goku forgetting to bring the paper seal was a plot convenience to extend the arc further. Otherwise, that would be the end of it. And personally, I would've preferred that way as it breaks the Power-Up Trope the show is well-known for. Very disappointed, but not surprised that the show is going back to the trope.
And then of course, merged Zamasu. Not Zack, or Blamasu, as how fusions work. But just simply "Zamasu". And we won't be seeing him in action until the next episode.
With the next arc of DBS to be announced at Jump Festa in late December, it becomes evident that the remaining episodes of the Future Trunks arc will move at quite a slow pace. I would expect the arc to end by the end of November, but it is possible it can go even through January. Toei had better come up with some REALLY clever writing to make this slow pace worth it.
NOTE: I've realized just now that Zamasu is voiced by Shinichiro Miki, who played Takumi Fujiwara in Initial D, the Japanese voice of James in Pokemon. And my personal favorite, Ryusei Date in Super Robot Wars: Original Generations. Now I keep thinking of Zamasu piloting a mecha while beating Goku to a pulp.....
