I have no idea what range villain has here and think the river call is just. Maybe raise flop?

Raise flop. Bottom 2p is pretty vulnerable on such a wet flop so get value now.

As played on flop, raise turn for same reason.

Call river. You only have to be good 20% of the time there and he has enough busted draws to get you there. You can't just put him on hands that beat you.
