Tengen Toppa Gurren Lagann

I recently watched Tengen Toppa Gurren Lagann, first when I read the summary, I was already interested. The first episode was great. Finally I finished it. The story has a few interesting plot changes. First, Simon's one and only important person left in his life, Kamina, dies. Simon gets all depressed, then he finally realizes he should be himself, and move on. Then another change of plot, where I think it was 10 years later, cities are built, and Simon is the chief in command. The story gets more and more interesting as it go on. A good 27 episode anime. Action/adventure/mecha based.
