This movie is perfectly watchable if you don't consider other movies like civil war, ragnarock & homecoming etc. This movie had lot to live upto and it didn't. Without spoilers the villain killmonger had all the potential to bocome a great and a momorable charecter. But too less sceen time really didn't help. This movies also has less "mcu fun moments" and the most disappointing post credit scenes of all time. You will know once you watch it (especially mcu fans).
In a nutshell: -
The good:-
1. Good visuals ( barring one scene where they do the coronation by challange ;))
2. Good action sequences
3. Second half gets better
The bad
1. Movie gets little preachy
2. Main charecter is bit monotonic
3. Almost no mention of mcu barring one flashback
4. Less amount of humour
5. Almost no repeat value
Conclusion:If you are not a die hard mcu fan you can miss this movie.
