Channel Five's soap opera reporting website Holy Soap said of the character: "While on the outside he looks like the perfect family man, he's actually a serial love cheat." Seven Network describe Sid as "his own worst enemy". He is an excellent doctor with a "winning bedside manner". Sid has never had trouble charming people – be they patients or co-workers. Seven Network also add that Sid "can’t turn off the charm, especially when it comes to women".

Relationships
In June 2010, Mammone revealed that Sid was to find a new romance with an existing character following his return. Mammone said "He finds himself quite attracted to a particular person in the Bay and he's quite surprised." He also said that Sid was not looking for romance or "anything to do with matters of the heart" and stated: "His focus is on his children. So when this comes along it's a really pleasant surprise." In July, it was revealed that Sid's new romance is to be with Marilyn Chambers (Emily Symons).

Departure
In May 2013, Mammone confirmed that he had departed Home and Away after previously hinting about a possible exit. Mammone claimed that he was written out because of "speaking up for the truth too often". He had previously criticised a cancer storyline involving his on-screen son-in-law Romeo Smith (Luke Mitchell) via his Twitter account. Mammone told his followers that he decided to re-write some scenes because they were unrealistic. However, Mammone was dismissed prior to making the public comments.
