Freuds Faults

We discussed today in class about how Freud had some theories that were not feasible and seemed to be almost comical. However, psychologists still credit Freud of being one of the most brilliant minds in the field. Do these theories in any way take away from his earth breaking thoughts or do his accomplishments outweigh the bad to an extent that we look the other way? I do not know the answer because i am not an expert in psychology, however, in other aspects of specialties i believe faults and false statements cause people to doubt much of what the individual says.
