It’s a mixed bag. They’ve been awful for a very long time due to the creative minds behind them either phoning it in and trying to adhere too closely, or wanting to put their own mark on it to the expense of capturing the themes and messaging of the original story - which is, quite honestly, unforgivable for an adaptation. People saying it’s just Hollywood are freaking deluded, too. The closest an anime film got to being good for a long time was the live action Ghost in the Shell.
