The battle cry of Monster Hunter apologists.
There's nothing to apologize for with Monster Hunter. It's filled to the brim with mechanics and concepts that are very intimidating at first but rewarding in a way very few games can achieve.
The first few gathering quests in the game take maybe two hours, max. After that it's just monster after monster.
The games could definitely use more in depth tutorials, that's for sure - but the effort you have to put into the games comes purely from learning all the mechanics, not from some sort of linear progression keeping you from the "good stuff".
In the last two games, you can even directly jump into the training mode and just learn about the battle mechanics alone.
