Yes, it should be easier compared to the classic version. Most of the boss fights have been made more accessible (some of them were pretty unfair and relied too much on memorizing patterns) and some annoying obstacles have been removed. The most important change is that spikes don't instakill anymore (except for one battle, though). Also, some enemies/traps deal less damage. And there are more save points now

Oh wait, I thought you were talking about the boss!
The monsters in your picture have a cycle: they look in a specific direction for some seconds, and then they look in the other direction. You just need to move while they're not looking towards you. They have been designed to be unbeatable. It's more like an stealth section
