Avengers Infinity Wars: Exciting, but Plot Sucks.

The Avengers are running away from terrible scriptwriters, but were unsucessful.  

Spoiler Alert!   Avengers Infinity Wars is not a movie, it is a trailer for the sequel, much like Star Wars 2 (Empire Strikes Back) left the bad guys pretty much in control, awaiting something great to happen in Star Wars 3.  

This movie also assumes that a complex plot is a good plot.  Doc Strange establishes that there are millions of parallel universes, plus the possibility of time travel, so whatever complicated terrible thing happens in Avengers 4, it can be undone in Avengers 5.  So I don't give a rat who they kill off in Avengers 4, and neither should you.

The action scenes are great however.  I watched this one in 3D and it is very exciting, even if I don't always know who is fighting or what side they are on.  Even here we have problems that bothered me however:

1.  When attacked by a horde of super powered aliens, it doesn't make sense to counter them by having Black Widow and Captain America wading in practicing kung fu. A machine gun is a better idea, although here it's surprising that ordinary bullets can work against these creatures. Conversely, a squadron of A-10s would definitely rid the earth of these pesky aliens. 

2.  Since the 3 Musketeers, good guys love to make wisecracks and exhibit a subtle sense of humor during battle.   However, you can't have the superheros make jokes while civilians are dying in the background. 

Honestly, my advice is to not see this movie.  Just wait for Avengers 5, and at that time read an online summary of Avengers 4 (which you will have to do anyway, given the plot is extremely complicated and difficult to follow).
