I agree with you yet I disagree with you. What I mean is that TRC is completely different from CCS. We really shouldn't compare them since all that is really the same in it is the reusing of characters. Which isn't bad since its what attracted a lot of us to TRC first of all.
Sakura converting a bad guy of many years is very possible. Sakura is pretty much useless right now but she soon gets better since she doesn't have a lot of her memories back. The manga of course is waaaaay better than the anime but the anime is loved by many due to the help of the improved art and the music.
The bad guy converting into a nice guy is a nice touch, although I see no point in it for the storyline. Still, it just shows that a person can change if they meet a significant person who has the ability to do that to them. In this case, Sakura. A person can have a change of heart right? Even if it does seem so sudden and unreal it can happen.
Even a person that's good can convert to bad in a matter of time. Example: Star Wars Anakin Skywalker turns into a bad guy and the etc etc. The way you live your life is chosen by you, if you wanna be good then so be it. If you wanna be bad, then go on. Nobody is stopping you. The rroad of life works in mysterious ways...lol
At first, I started critisizing the anime for every minor thing because I figured the anime should be completely near perfect. I was proven wrong of course. But now its gradually getting better now that I haven't been whining about every small wrong detail. We all just had high expectations of the anime and judged it from the first episode and so on.
We all need to let the anime just go on as it is. Were not the creators, just fans who love TRC but we have no right to tell the makers how to do this and how to do that. Hmm...this got pretty long. XD Anyway, the manga is still way better than the anime but the anime is coming along nicely if they keep it up the way it is.
We all expected that it would be different from the manga so there you go. Its different.
