I've tried Tasty but it didn't panned out

Recently tried cooking this recipe from Tasty, Slow Cooker Honey Garlic Chicken, but it turned out horribly wrong. It looks easy and simple but somehow didn't taste as nice even though I've followed the instructions to the core.

Firstly, it was salty perhaps from too much soy sauce. Secondly, hubs didn't like the oregano taste. Well, overall it tasted weird lah. Last but not least, it didn't turned out like the video. You can view the exact video here:

Here's my update:

My ingredients

All in the slow cooker

The all blacks...

My only mistake: I didn't taste the mixture first before putting it into the slow cooker to cook. I should have tasted and corrected it before proceeding further. Lesson learnt... just stick to the likes of Jamie and Nigella...
