A handful of pathetic jokes/decisions get in the way of a perfect comedy

Rating: 9/10 (12 April 2019)

I adore every single character presented in this movie. I liked the (quite dark) main story. I loved every character side story and the development from them works perfectly to me. I laughed at almost every joke, and the lazy exposition didn't bother me at all. Actually, I found it interesting and I was happy to know more about it from Russell's charming presentation (it was kind of a presentation).
But there are a handful of decisions/jokes that I totally hate and despise, and made the movie flawed:
1-The Taserface "funny" scene. What was that? It couldn't possibly be a worse joke with a worse execution.
2- Ego confession to Star Lord that leads to his demise. Again, an ironic idea with a terrible execution.
3-David Hasselhoff cameo. Totally unnecessary and hateable.
4-Exaggerated "emotional" Rocket/Yondu scene. Again, a lackluster execution of a great idea that I totally buy.
5-The Pac Man was too much.
But that's it. I love the movie.
