It's not that it is old English, that isn't the worst part. It's that it is effectively a play, or "screen play". It's a truncated version of what a real novel is. It has no settings, no support, just straight dialog. Every incarnation of Shakespeare has tremendous liberties taken by production companies to set the stage, setting, ambiance, mood, etc. This is NOT to the credit of Shakespeare, and more to historians and play companies.
It would be like praising a screen play as a great novel; it's incomplete!!!
The reason why Shakespeare is forced down our throats, is that is really the first comprehensive body of work that encapsulates the English language to formalize it, when at the time, every village and region in England had a different dialect. Shakespeare marks the start of the rise of the English language on the level of French or German or Latin. Latin had been formalized ages before, and French had been formalized more recently compared to English.
Shakespeare should be studied more for historical value as opposed to literary value. More so with the controversy over authoriship, credit should be spread around.
On a similar topic I read the translations of a few of the old Latin Epics such as Aenead (even read that one twice just cause I enjoyed it that much), Metamorhosis of Ovid, etc. as well as some random Norse stuff, Homer (Greek), Gilgamesh (Babylonian), and Ramayana (Indian). and I enjoyed most of them BUT, I ried reading Dante's Inferno THREEE times now and I always loose interest and stop about a third of the way in so i came to the conclusion that it sucks! I'm sure the poetry of the original in Latin is beautiful but the poetry is lost in translation and what's left is a fairly borring and uneventful story of a guy walking around and talking to ghosts. Literally NOTHING happens. Not only that but you literally have to read pages and pages of background history of Florence and Dante's life to understand half the references and who the ghosts are and this is coming from someone that read most of the epics that came before this one so I'm already familiar with most of the fictional characters that appear in Inferno/Comedia. Arghhhh! So yes, in conclusion; Dante's Inferno sucks! I actually prefer some Shakesear to Dante by a long shot.
