- Inconsistent characterization (major discrepancies in established characters vs actions, even taken in context) - Uneven plot (too many divergent sideplots vying for attention and the main plot themes are never really explored as a result) - Bizarre pacing (the movie takes too long to get going then overstays its welcome when it does)
The Honest Trailer for it totally demolishes most of the major points but it is far from exhaustive in outlining the movies issues. You don't have to be a nitpicky spergelord to pick up on these things either. I don't really care about buddy taking off his helmet for example but there are a ton of egregious examples that go way beyond nitpicking a small point.
