Those were the days! I loved the show back then and a am disappointed with the show at the present. Things I enjoyed back in the day:
1. Ash
His old voice, 10 year old attitude, and funny actions. This kid made the show for me, and misty and brock enhanced his personality. One thing i thought was funny is dealing with his hat. I did like the cap-twist when battling, it made anything more epic than it already was. But that's not what i thought was funny. He made such a big deal about his hat in the Mankey episode, about how it was super rare and everything. Then he just tosses his "super-rare" hat for a normal one when going to another region. I mean, come on. Another big aspect was his excitement. He was totally into anything pokemon related and it made the show a whole lot more enjoyable. The caterpie episode is the best for showing his awesome personality. The excitement of his first capture, that cow-terpie joke, misty making fun of him! Good stuff, and one of the best moments in the show.
2. Brock and Misty
These two characters also put their own magic in the show. Misty has more personality then the other two girls combined. I loved her fear of bugs, and the way she would constantly put Ash down. The other two girls are too nice. It was also funny how she put Brock down too. Plus her interactions with Psyduck were classic as well.
Brock, why did you change so? He was always so smart and mature in the old show. He still is, but he doesn't have that gym-leader feel. It seemed like he couldn't make a mistake, and Ash looked up to him. I think they toned down the whole girl-obsessed thing, which was a very humorous part of him. But instead of mentor, Brock's only purpose in the show it to give Ash and Dawn food. It really pisses me off, because that is seriously the only thing you see him do. It started in Heoen and never stopped....
3. Pikachu
When coming out of its poke-ball for the first time, this was the cutest pokemon ever. Its awesome chubbiness is long forgotten, but i guess that's because it got older. I loved the personality of pikachu back then. The whole ketchup obsession and shocking Ash were two things i will never forget. The old show had pikachu interact with the other pokemon a lot more. Not in the fake friendly way like the show today, but doing random and hilarious things.
The pikachu nowadays has no personality at all and you know when he's gonna say that "pika-Pika" line. I mean there's like a million scenes with him and Ash on a hill, over looking a gym. "You ready Pikachu?" and then that line comes.....arg.....I loved when Ash would would to call pikachu out and pikachu when be randomly in a bed, OMG Ash's faces were priceless.
4. Team Rocket
These characters were so evil and awesome back then. They have been washed down so badly, they really shouldn't be called "evil" anymore. Jessie and James are so different from how they acted back then. I would even say the James came across as dominant to Jessie in those first few episodes. Meowth is pretty much the same, but i liked the old voice better.
5. Daily life
I liked the old episodes because of how real they seemed. Pokemon were mixed into everything, the architecture, decor, house-hold items. You would see pidgey's flying overhead and people using their pokemon for daily chores. It just gave the whole thing a more realistic atmosphere. I think the new show dimmed this down a bit.
6. The cartooniness
This is what made the show fun. The random, over-played emotions, misty beating Ash and Brock, pikachu's antics. New stuff is seriously lacking this.
7. Gary
I don't care what anyone says, Gary pwns Paul, as a character anyway! The way he would make fun of Ash was always so funny. Just everything about him made him an awesome rival:
1. Pro. Oak's grandson, reason to brag to Ash
2. He had his own Car! Does paul?
3. He had a fan club, which Ash and Brock were jealous of.
4. He was always WAY ahead of Ash, he even had badges from other regions before Ash was finished with the 8 kanto gym. Paul was ahead of Ash, but not by much.
5. He out caught Ash during Ash's "gonna catch'm all" stage, making Ash even more mad at him.
6. His electivire, who Gary didn't have for very long, beat Pikachu who Ash has had for his entire journey, and who Beat Regice.
Gary was an awesome rival for Ash. I'm not saying i don't like Paul, but he doesn't compare to the rivalry between Ash and Gary.
I could say many other things i miss, but i'm too lazy today....
