Well it's not necessarily the fact that you have a mixed opinion that is the issue
The video concept takes precedence over the video content when it comes to what determines the packaging of the video
The video concept has an overarching effect on how good the video content and packaging will be, that's why video ideation is a skill youtubers have to develop
Because you're turning old written game reviews on a blog into youtube videos, you already have the video concept pre-determined
Just copying those reviews over into a youtube video isn't giving you any flexibility in video ideas so you end up having little control over how good you can package the video (i.e all you had to work with was that you had mixed feelings on amnesia)
That's why I said you would need to do some work to reformat your written reviews to have a better thesis so they can be transformed into youtube videos
Those written reviews you have really should serve as a kind of outline or catalogue of ideas that you pull from to then create a video that says something interesting and lends itself well to having appealing packaging
Using Jacob Geller's video as a case study again, when he talks about amnesia: the bunker, he isn't talking about what he liked and disliked about every aspect of the game
He for sure is still reviewing the game and explaining what his experience of playing the game was like, but he's selective in what he presents to the audience because his thesis isn't "here's all my thoughts on amnesia: the bunker", it's "here's me breaking down my experience of amnesia: the bunker by explaining how it instilled terror in me throughout game with various game mechanics that is unique to other survival horror games" which of course connects to the main video topic of him reviewing three horror games and analyzing how each instill terror in different ways (i.e Three Specific Kinds of Terrors, the video title)
