"Contrary to usual belief "THE TEMPEST" is a badly constructed play;it lacks the conflict which is the essence of a drama"Do you agree?Substantiate...

Of course, this question is purely subjective, and the
answer depends entirely on what you see in the play. I disagree that the play contains
no conflict. It perhaps may not follow the "norms" for what happens in
Elizabethan/Jacobean drama, and many people think that the play was Shakespeare's
farewell to the stage.  Still, the play is character-driven, mainly by Prospero, and it
holds plenty of conflict. 

Prospero experiences conflict
with nearly every other character in the play, from his daughter Miranda, who would love
to get off the island, to Caliban, his unwilling servant, to Ariel, his willing servant,
who yet wants to be freed from servitude. 

The story began
with a long-ago conflict that caused Prospero to be banished with his daughter.  He is,
at the time the play takes place, trying to bring a resolution to that old conflict, not
just by settling a score, but by providing for Miranda's future.  True, things may work
out fairly smoothly, but that does not mean that conflict does not exist in the play. It
only means that Shakespeare was a master at dramatic resolution.
