To me, it is.
Since the pandemic, movie theatres have been a no go. Now, I have invested quite a bit into my own home thetre and Infuse is an important part of it. It is better than Plex when playing 4K movies cause while my Plex client on Apple TV feels it needs to transcode 4K audio (and video as well if PGS subtitles), Infuse does all this without any fuss.
So at 75 bucks, it is 2 trips to the theatre for me and my wife. I feel I got my money's worth
