Game difficulty (Gears of War)

Good day, everyone, I understand that it is now 2016 in the yard!
The game was released in 2007, 8 years have passed, many have completed the game, etc.!
But I have a question - do you think the first part is hardcore or not?
Personally, I have not yet been able to master the normal mode, I seem to have passed the game only in two modes, half on normal + at the end on an easy level of difficulty!
Describe how difficult the game is for you or how easy it seemed ?!
