I have not seen the first movie, but generally I am a big fan of Marvel movies and normally I don't mind a silly plot as long as you have fun But this is the first movie in ages where I seriously considered stopping the DVD and watch something else.

Story is dull, actors are wasted. Most of all, I could not bring myself to like any of the characters, they were all dull and replaceable.

It was completely unfunny, all these discussions with the symbiont were wooden and dull.

And casting Harrelson as a villain more often does not work than work.

If you have another DVD to watch, pick the other one. For example a movie from the MCU.
