For the most part it isn't, but at the beginning, provided you read what she is actually saying, she will mention the monsters and the ruins and how you have most likely experienced them all before.
Episode II is definitely more challenging than Episode I. In episode I, hardly any monsters have special things to them. Chaos Sorcerers use techs, Chaos Bringers have a charge and firing special, and Belras can fire their arms, but for the most part it is walk and swing at you.
Meanwhile, in Episode II, there is all that, plus Sinnow robots that can turn invisible, one of them will disarm you, there are turret traps, the Gibbons use techs, there are mini bosses, the main bosses are much more difficult, Delbiters will charge way more than Chaos Bringers, and there are monsters in the Seabed level with an ability similar to Dark Falz, it will glow and become immune to anything but Tech attacks, they can also fire a laser at you as well as hit you close range with prong-like attacks.
I hope this is all you need to know about Episodes I&II.
