In the Iliad?
Paris is barely ever seen with Helen in the poem, and there's no plot-development of their relationship. Besides, as far as the structure of the poem goes, Paris is at best a background character, and Helen almost doesn't show up at all.
Most people, when they try to shoe-horn a love story into the Iliad, try using Achilles and Patroklos' relationship. It's still not a great fit. Achilles is almost invisible for half the story, and Patroklos really only shows up to put on Achilles' armor, lead the Achaians, and get killed. The only thing we see of the relationship is what it leaves behind: a petulant man-child killer who goes apes**t on gods and men for days after he loses a prized possession. Much of the plot of the Iliad is Achilles throwing b***h fits after losing something; in the beginning, he loses Briseis and retreats to his tent to sulk while his comrades are slaughtered, then he loses Patroklos and kills everything within reach until his rage is slaked.
At least there is plot there - a bit of it, anyway - and there is a relationship, although it's not entirely clear if it involves love. You could make an argument for it.
But then you'd have to identify a villain and a hero.
That's part of the reason all the literary greats just never appealed, the most exciting thing is to read about the actual battles and stories themselves. Shakespeare, Homer, these are all just famous as the teller of the story, not the subject or embodiment of it.
Another example has been reading the clash between countries during the Napoleonic wars, they are just so intense and filled with actual drama. In all seriousness, who would rather meet Shakespeare than Napoleon? A funny whimsical pleb who writes stories so ineloquently you need to have it translated for you by a cadre of individuals, or a man who literally conquered pretty much the entire civilized world.
Or even Shakespeare's dramatization of the English with John Talbot and his silly absurd story about him being a heroic figure, the French annihilated the English at the Battle of Castillion, which was part of the larger hundred years war which was the English encroaching on French dominion anyway. If you lose, you aren't a hero.
Not to mention all the funny things you learn like that a German victory in WW2 was interrupted by friendly fire (and I'll bet friendly fire happened in the Peloponessian war, but that didn't make it into the epic), or that an actual bear fought on the side of the allies and transported ammo crates

As far as Homer and the Odyssey and antiquity goes I haven't explored it as in depth, but there were certainly some feeling like that this seems all high strung and emotional when it should be about some kick butt Spartan hero. If I just read about for instance the Battle of Canne, it's all momentous and engaging, because then it leads you to ask if Hannibal was such a bad mother why didn't Carthage win the war? And well it turns out that however clever Hannibal was, Scipio was like a god compared to that...
