On top of everything else, I'm participating in a saga course at uni, where we read four sagas during the two months and discuss generally about Icelandic sagas and their features. This type of introduction is priceless, because it helps to understand how and why sagas are an integral part of Iceland and its history (even today they influence Icelandic authors, and twenty years ago The Book of Icelanders was read as fact in elementary schools).
I somewhat grew to like the simplicity. William Morris's translation is still terse, but also flows beautifully, and the archaic expressions add texture to the language. The form does take time to get used to, but the context and purpose of the sagas explain the presence of family trees, whose presence might seem pointless at first. It's debatable as to how much of the historical aspect of the sagas is true, but they were originally intended as records of history as much as stories about the exploits of certain Icelanders (saga genres vary from family, kings', romances, bishops' etc.). The family lists in Gunnlaug places it in the family saga department, but I don't think it's necessary to remember all the characters, as some of them are there for other than storytelling purposes.
After all, when everything else except the basic storyline is stripped away, what's left is an entertaining and tragic story of Gunnlaug's efforts to be a better man and win Helga as his wife. People throughout the ages have had similar worries and desires, so when Gunnlaug's proposal is rejected by Helga's father, because Gunnlaug is too restless and about to go abroad, some of us can recognize the father's need to want only what's best for his daughter. Gunnlaug therefore departs, and I assume he's welcomed as Helga's fiancé only when he has gained experience and capital.
Echoing Greek tragedies, there's foreshadowing, and the idea of fate eventually catching up on you is carried throughout the story. Foreshadowing can be off-putting sometimes, but in this case it was interesting to see how the events unfolded into the inevitable tragic outcome. Dreams reveal the life of your son, the suffering your loved ones will endure, and no matter how hard you try to escape them, you will be caught by the superior forces that inhabit your enemies.
The saga of Gunnlaug still focuses surprisingly little on what the various family members mentioned did, but I expect some of them will be explained in other sagas. The historical context is only brushed lightly upon by explaining with a few sentences what's going on in the countries where Gunnlaug's travelling. King Ethelred seems to have no problems with Icelanders, but warns Gunnlaug of a Norwegian viking who lends some money from Gunnlaug. Really though, how stupid are you that you just decide to lend money to a complete stranger, because he does after all promise to pay it back! Christ...
Speaking of Christ, the writer of the saga seems to have a problem with pagan traditions: "Next to this befell those tidings, the best that ever have befallen here in Iceland, that the whole land became Christian, and that all folk cast off the old faith". Perhaps not surprising, but the era of Christianizing the Nordic countries is fascinating. Obviously I disagree with the author, but at least his own misgivings and attitudes towards "heathens" don't interrupt the story too much. When in doubt, just wield your axe and all your problems are solved (or not.)
The characters are mostly described in black and white terms, but Gunnlaug's perfection does suffer a small dent when you start to think about the purpose of his journey. Who cares if you forget your promises made at home and wander around in kings' houses and enjoy their hospitality for way longer than you were supposed to, even though poetry is clearly not appreciated anymore? Maybe there's a diplomatic aspect I don't understand, but Gunnlaug adds a sense of ambiguity to the saga's characterizations.
Overall, the fairy-tale like repetition and redundancy won't stop me from reading more sagas. This one at least had a quality of magic and adventure, and something about the pagan era fascinates me to no end. In this case, simplicity leaves more room for imagination.
