The 1981 TV series did a fine job, likely in no small part thanks to having Adams himself around and involved.
I feel like any future HHG adaptation would need to be TV rather than theatrical film. That universe is just too full to condense meaningfully into a 90-minute blockbuster meant to keep the Hollywood lowest common denominator in their seats. You need room for all the multilayered apparently-random stuff interacting with each other in the particularly bizarre ways Adams was so good at pulling off, and it needs to capture the whimsy of the source material without devolving into the unremarkable formulaic stuff the latest attempt to do Dirk Gently on TV turned out to be.
