Poor Celestia, she's so underrated compared to Luna.
I think in Season 4 she should have an episode in which she decides to stay with Twilight in Ponyville while she teaches her about being an Alicorn. That might be interesting.
Also, many people hate the fact that she banished Luna to the Moon for 1000 years. They obviously don't know that she was Nightmare Moon during those years, so she would need a lot of time to think on her actions. Besides, she had to think of a quick solution before more damage was done. Like it stated in the first episode, 'she tried to reason with her' shows that Celestia is calm and patient, and will often try a non-violent method first. Also , when she got defeated by Queen Chrysalis in 'A Canterlot Wedding', Chysalis had consumed Shining Armor's love energy, making her far more powerful.
Wow, that was a long post for an iPod. I'll get some pictures later.
