Nothing is perfect, but the preponderance (warning: generalization ahead!) of Comcast- (and Time Warner-, Cablevision-, Cox-, Charter-, etc.) -bashing is either people misunderstanding the level of service that they've purchased, or just expressions of frustration that the company has the gall to charge them what the service is actually worth to them, instead of some lower amount.
The best indication of whether folks are sincere about their concerns about Comcast (Time Warner, Cablevision, Cox, Charter, etc.) is generally (warning: generalization ahead!) whether or not they've switched to FiOS or DSL yet. If not, then they're probably (warning: generalization ahead!) just whining -- basically understating the value of the service they're receiving, to justify their criticisms. If yes, then they've probably (warning: generalization ahead!) evaluated the services, and actually found Comcast's (Time Warner, Cablevision, Cox, Charter, etc.) lacking.
