There are several serious problems: the style is uneven (because of the shared authorship - a theory I completely buy); the Alcibiades plot is rather bolted on; several significant plot events (including Timon's death) happen off-stage; the pacing is very weird (where most Shakespeare plays have a significant moment in Act 3, here the key scene is not until the end of Act 4); and Timon himself is a rather uninspiring hero, a poor reflection of Lear and Hamlet - so much so that I really wondered if the accepted chronology might be wrong and this a trial piece for better known and frankly superior works.
No doubt a good actor and inspired director could make a great production of this (and no doubt several have). Arkangel has made a good effort with Alan Howard in the title role. But it seemed to me surprisingly thin.
