I liked the Orange League (suddenly, at nearly 9 PM, I get cravings for orange fruit juice sticks XD), it was original.
And the Champ, with his necklace-Pokeball, is coooool. I now draw all my new Gymmies, which suck, with a Pokeball necklace.
EDIT - Frostweaver, I half-agree with you. The plots were all boring and, yes, monotonous - e.g. Gang meets gal/boy/family in trouble (here, Brock falls in love with any females around), then TR makes trouble, gang smashes TR into the sky - how do they live that long? 0_o), they fix up the trouble, TO BE CONTINUED.
Some of them were interesting. The first two movies were definitely good. I like the short clippies, they're cute.
Although I don't reckon Orange should be forgotten. Sure, they probably will, but they were - out of the monotony.
a) Nintendo's 2-on-2 R/S battle thing originated there (WOOT!)
b) There were only four Gym Leaders, something different.
c) Tracey was around then, so cool.
d) The eps were more interesting, because there were more complications.
Although the Johto eps were CRAP with a capital C... (And all the rest in capitals). The Hoenn ones aren't that bad; they're good for shipping. :)
