He's trying so hard to put it all together and bring a refined performance out of a group of actors that haven't got a chance of doing anything serious with any degree of class. Obviously, the role was written with the intent of making him comic relief, but there is still a very earnest and good core in his character's soul.
A hilarious, courageous yet naive fool. He's an important part of the plot, being Titania's temporary boyfriend and the 'overactor' of the group of workmen! He's a pretty funny guy! :)
