There's work that's excellent, but does not appeal to me. I can still acknowledge and appreciate it's excellence and learn from studying it. I offer the "friendly" amendment that it can also be useful to study that which is not only unappealing because of personal taste but also reflects poor design, execution, or incoherence, to try to understand what about it fails. Then try not to do that (again, if it's my own work that disappoints).
