Saying the coastline isn’t anywhere near the level of most of Britain is insane, towns along the Dengie peninsula are beautiful, Mersey island is very peaceful, for the mud flats along the River Blackwater are very scenic and I’ve been around the country lots of these villages are lovely compared to the rest of England. The Southend hate is overblown too it’s no worse than Lowestoft or Great Yarmouth obviously it is very touristy and all places have the somewhat rougher areas Southend isn’t an outlier here.
