I thought they were pretty much consistently average.
The first Matrix film was greatly over-rated (probably because it wasn't TPM) and the other two greatly under-rated.
Visually they were the kick off point of a lot of recent cinema tropes but they are all very passable science fiction action films.
I avoided watching the last one for a long time because I didn't care much and it was almost universally slagged off but when I finally got around to seeing all three together about a year ago I found them all rather enjoyable.
Nothing that amazing but for what they are rather watchable.
