The boss battles weren't that hard. The issue was the un-skippable cut-scenes.

Generally. I don't like playable dream sequences or artistic filler sequences in games. I feel like there are a lot of people that working in gaming that couldn't get into Movies/TV and as a result try to insert that sort of story telling into a form of entertainment where it doesn't belong.

The best in game story telling IMO was the Doom 2016 game, where the physicality of the character was done through the short sequences where control was briefly taken away. Unfortunately they undid this (mostly) in subsequent sequels .
