Beiser's book fulfills the aim of the Routledge series of providing contextually informed introductions to the great philosophers (it does this better than the books on Kant and Schopenhauer). In situating Hegel so well in his intellectual context, an approach which is of course fitting considering the importance of wider culture and society to Hegel's thought, he helps the reader have some sympathy with the ideas. I didn't agree with all of Hegel's speculations, but Beiser succeeds in making them never seem pointless.
Beiser sets up his detailed discussion of Hegel's arguments very well with the introductory chapters. Beiser, like most Hegel scholars, describes Hegel's motivation as the attempt to overcome the frustrations of Kantian thinking and the disappointments of the Enlightenment. Beiser does this better than most by showing how interlinked these two concerns were in the mind of a young Hegel first turning to philosophy. Hegel first aimed to be a pamphleteer for Enlightenment, Kantian values, but in the face of events like the Revolutionary Terror thought that Kant left much philosophical work undone.
The subsequent chapters fill out this programme, with Beiser always grounding the grand speculations in the concerns of Hegel's time. Beiser even makes the vaulting ideas about Geist less daunting and alien. Apparently he first developed the concept when discussing the mindset of lovers: like Geist they go outside themselves and realise themselves in another.
Beiser's excellent study is itself a persuasive case for his way of writing commentary, namely part intellectual history, part exposition of the arguments. Philosophy students will need to go on to more focussed books (Houlgate is good for the next level), but this is a rich, interesting study that you'll wish other scholars emulated.
