Worst artists in the world?

Wood

McGonagall

Was William Mcgonagall the 19th century Ed Wood?
 Whilst it would be great to get Johnny Depp to play the official worst poet in the world (Vogon poetry doesn't count), are there any parallels between these two curious cultural icons?
 Both are regarded as the 'worst' in their fields. Not merely bad, anyone can simply be bad at something, but comically bad. Their work contains what the industry and the public regard as elementary errors that are so apparent that they are comical.
 However, the key is unintentional errors. If the errors appeared to be intentional, then they would lose their comedic appeal. The comedy arises from the delusion of greatness.
 William McGonagall was poet, and didn't he know it. His poems inadequately use poetic metaphor, and don't scan properly. Here's a sample of his most famous, the Tay Bridge disaster:

Beautiful Railway Bridge of the Silv'ry Tay!
Alas! I am very sorry to say
That ninety lives have been taken away
On the last Sabbath day of 1879,
Which will be remember'd for a very long time.

 Edward Wood was an American filmmaker from the 1950s, who produced, directed, edited, authored, and starred in his own films. His productions were B-movies, with little commercial success, and were also created by his enthusiasm and lack of recognition of his limits. It was only decades later that his movies acquired a cult status, and as a result he is one of the most famous movie makers of Hollywood.
 William McGonagall also had no care for recognition from his peers, and made his money from performing his work in front of a crowd. Audiences would jeer and pelt him with fruit, for which he would recieve up to 15 shillings a night. He seemed to believe that the queen had enjoyed his work, due to a polite letter from the palace thanking him for his poem, and tried to perform for the queen after walking from Dundee to Balmoral. He was stopped by security. Whilst it has been suggested he was playing up to the crowd for money, I don't think this is the case. He went out of his way to perform, going over to America or walking 60 miles to see the queen, the sort of poetry most people write in primary school. I think he genuinely did believe in his talents. Like Ed Wood, who continued in his career long after common sense should have told him to stop.
 Both died penniless and were cruelly mocked by their peers and the public. Both had to be rediscovered by later generations. And both took mediocrity and produced strangely timeless work that's quite enjoyable.
