I don't really think so. I thought the arc was pretty poorly put together in some places. I suppose the arc was supposed to streamline Team Plasma's plot by mixing together elements from BW1 and BW2 but it overlooks all the best aspects of Team Plasma. I really don't like their shtick of Pokemon liberation was nowhere to be found. I mean, anime Team Plasma is basically no different from Team Rocket. Minus Ghetsis manipulating N and Helena/Verbana, everything Team Plasma does in Episode N could be done by Team Rocket and nobody could spot the difference. Also, while freezing Ghetsis and friends solid and trapping them is kinda inspired, the show really didn't earn it. Ghetsis never even says one word to any of the main characters besides N. (But then again, the finale episode in general was disappointing)
I'll just quote another post I made about why I really don't like Episode N.
While Episode N probably was my favorite part of BW, I don't think that it was handled all that well either. They ignored everything that made Team Plasma the most interesting out of all of the evil teams for me and turned them into a generic group that wanted to control Reshiram because of reasons. To be fair, it would be kind of difficult to pull in enough elements from the B/W storyline at that point of the series and I think that the sequels being last minute decisions threw a wretch into the works, but it was really lackluster to turn the group into such a generic bunch. The organization didn't even feel that large, despite having the resources to revive a bunch of Genesect, considering they had the same grunts present in most of the Team Plasma episodes. Ghetsis was a pretty much inactive until the last episode and even then that wasn't much.
They did get N's characterization from the games pretty well, which was nice, but seeing more of his character development on-screen, instead of doing that primarily off-screen, would have been nice He had moments where meeting others while traveling with Ash and his friends affected his view point, such as realizing that the Pokemon in that harbor patrol wanted to save people instead of just doing what they were ordered to do, and if there were more moments like that, it could have helped to make the arc more interesting. Doing that mostly off-screen kind of weakened his potential though. Colress's characterization was also kept fairly well.
The pacing was a bit lackluster too. They rushed through the League to get to Episode N, but then rushed Episode N to get to the Decolore Islands arc. The ending was pretty anticlimactic, especially when Charizard didn't do anything significant after they made a big deal about its return. The arc had some good elements and if it had a bit more time and better execution, it probably would have been a much stronger arc than it actually was.
I agree with Robo-Floatzel, who said it was expiremental. I think, though it wasn't great, that it's really cool that the anime tried something like this. We've never had a true villain arc, while Aqua/Magma/Galactic did exist their stuff was mixed in with the main plot. I wouldn't mind the anime doing more stuff like this instead of just League/GrandFestival/Battle Frontier arcs.
