I really enjoyed this saga. Although the writing and pacing for the first dozen episodes was below-par, it finally got going with plenty of incident.
This is probably the first season where I had watched a RAW version of an episode, and what better time to watch one than this. I loved seeing Ash's old pokemon return for another shot in the limelight, as well as seeing more development for the main core of his team (i.e. Pikachu, Swellow, Sceptile, Corphish and Donphan), as well as May's. However, I guess we can't really say the same about Brock's lol. The trainers themselves, including Team Rocket also got plenty of character development, which was great to see.
A couple of gripes I have, though. This would've been the perfect opportunity to go back to the Kanto that we all familiarised ourselves with on Ash's first adventure. It would've been fabulous to see how many of the filler characters had progressed since Ash had first met them, as well as providing us with some anticipated reunions. Hey, whatever happened to meeting Samurai for a re-battle, or AJ in the Pokemon League? How about searching for Pidgeot and Primeape to see how they're getting on? Oh well, that's water under the bridge now
. Additionally, that would've taken a lot more time to cover. I was also a little disappointed that certain other Pokemon of Ash's weren't given time to shine (i.e. Johto starters, Noctowl, Muk etc).
On the other hand, the battles were amazing. Charizard V Articuno was entertaining enough (although it would've been better to have seen Ash use rentals in my opinion), and it was also awesome to see Ash struggle against the Regis (Torkoal V Registeel was a great battle). I wasn't, however, too delighted with the decision to have the Kanto starters take on Brandon in the final battle. Although I found it cool enough to see them reunited once again, it would've been better to see Sceptile, Swellow, Corphish and Donphan get one last hurrah before they were inevitably Oak'd.
Despite these gripes though, this was one of my favourite sagas, and I was just as pleased with what it offered than without what I feel it could have offered.
