If it is a one sided battle then there is nothing interesting to watch even if there is a million spectators and West Indies and England is not going to be a close match either as England might dominate them.
This is the main problem which I observed with test matches. Only popular series like the Ashes etc are usually viewed by test enthusiasts while the rest are usually viewed as highlights on YouTube etc.
This is how I watch tests myself though I am not a test enthusiast. Also, England could face some issues even though they are technically a way stronger team due to the COVID effect. West Indies could surpris them if they bowl the right lines and lengths.
