The fact that Boom is a Sonic game was a factor in the game's low scores from reviewers due to the lack of speed, but that's about it.

The reason why Sonic has a bad reputation is simple: There have been a fair amount of bad Sonic games. However, Sonic games aren't considered bad purely because they're Sonic games, a number of Sonic games have been given good scores by reviewers (even IGN, who everyone here hates for being biased towards Sonic) in fact, recent games such as Colours and Generations got good reviews.
