Whilst I am not a "Trekkie" per se I have always appreciated the franchise and Nemoy's Spock is arguably up there with Vader for iconic sci-Fi characters.

Nemoy definitely was a talented practitioner of acting and his passing definitely is a big loss not just to the Star Trek fans but to acting in general.

One of the 'greats' of the 20th Century gone IMO.

RIP Spock.
