I haven't read most of Tezuka's manga, but as far as anime is concerned, he sure isn't very good. He seemed to lack some basic discernment, much like Tomino does for example, and littered his shit with unbecoming tonal shifts and jokes that have no place and exist merely cause he thought it would be funny. When reading some of his titles, it is common to have the flow interrupted by some visual gag and I wondered just why it was there to begin with. Cleopatra is a disaster in most senses, starting with its premise that sounds like one which would be promptly refusedby any funder with more than two brain cells. The movie goes and goes and as you realize it's absolutely all over the place a thought arises: why does this exist? There aren't bad jokes interrupting a relatively thoughtful story... there is no thoughtful story and the whole thing is the bad joke. It's a wholly half-assed product made out of toying with history without the quality control, tonal consistency, and self-awareness required for it to be minimally interesting to watch. Tezuka's self-indulgence can seem nearly solipsist at times, but sometimes that means utter boredom for the audience as absolutely nothing matters if it's just a piece of incoherent mess with bits and pieces of cultural and historical references. The Animerama project consists of two ill-conceived pieces of shit followed by one cleverly crafted arthouse masterpiece. Guess which one Tezuka did not work on? You're right on the money.
