He wasn't universally loved and was often criticised for his mistakes, absolutely correctly.
But, his infinite passion for the sport (not just F1, by the way) and his ability to transmit that to millions of viewers was unmatched by any commentator in any sport, in my opinion. So many of the races he covered in the '80s and '90s were dull, in truth, much more so than the average Grand Prix today - and he is a big reason why so many fans believe the opposite to be the case.
RIP Murray.
