I think the same about season 4 to a point, but i stop short of complete critisisim.
The reason why this is portrayed to give you the extra dimension of the first intergalactic love affair. and how it works out - but of course trip gets blown up and killed to save the crew from terrorists in the end, and known fully well if he had a little different future that child from a different dimension would of been theirs.
But there are other reason why i stop short, Because there is

of fighting, destruction, and for couse Shran.
I can nott wait to watch it all again. it's all good because it's not like the other Star Trek series where everything is free and not enough tension. this has it. I was always wondering... what would happen to the Enterprise next? The Tholians come back? The Suluban destroy the ship? Or do the Romulans plan another mine test?. My 2 cents.
in order of overall quality. IMHO.
Enterprise.
DS9.
VOY.
Original.
TNG.
