No pun intended - the movie feels a bit like a redemption tour of the main actor. Jan Josef Liebers made some very strange observations during a time where the world was even more sensitive than before. That said, he was not alone in experiencing backlash to stuff that were said.
But while this has some cringe worthy moments (quite a few actually), this also has an uplifting story overall to tell. That is, if you are able to forgive the movie and the character. Because what the movie is not telling you or rather what the main character does not understand on his journey (he does learn mind you), is not that he says something wrong ... but how he reacts to it! Now one could argue it is because the person is afraid of the cancel culture ... but that would be lying to oneself. Because you can make a mistake - but to be a grown up you have to own it.
What our main character is owning: is his family and his own speech! Also he is pitted against a greater evil (actually two of them, so a bit too much to be honest) ... so he already is winning in that department. So while there is a lot wrong with the movie - or you could argue that the movie gets more than a couple of things wrong (life lessons and all that) - you can be forgiving and just suspend your disbelief. Like with how the movie starts ... our main character in a fantasy - being a native American. Again not really making the most out of what they present ... not to mention the incorrect calling of said ... people! Everyone knows of Cowboys and Indians ... it is ok to call them that too. But as a grown up you should be able to also know there is a different term for them (native Americans as I already stated).
Sometimes things go to far ... that is true. But the movie is not about nuance ... while it does try to convince with caricatures and real issues some struggle with ... there is intent, that people will be able to see with what you say. The world is changing - and we should be able to change with it. Maybe this movie will help (even if this is not the initial intention) along the way ...
