Most of serials I started watching after few episodes were over and left half way (once key story track got over). Let me recollect such serials from last 5-6 years. I have include Hindi serials as well and all are in random order
Colors Marathi
Assa sasar surekh bai - on and off till Jui and Yash confessed their love to each other. But lost the interest when CV started portraying chalel life is best and ambitious Yash became dumb
Tu maza sangati - Initial des episodes for young aawadabai and for interactions between tukaram, his parents and his first wife
Saraswati - started watching after Saru and Mothe malak marriage then catch old episodes on boot. Followed it till 1st 200 episodes, then watched Dubai track and stopped watching when once gripping story-screwnolay went for toss. Started watching again after Durga entry. Titeeksha played Durga also very well..She and Astad recreated old magic till original saraswati reentered. Then story again turn illogical,then aasta left the serial for big boss. But I watched it only for titeeksha's double role till Durga completely turned negative.
Tumchyasathi kay pan - could watch it only for couple of minutes at a time
Ali lahar kela kahar - Started watching for Prajakta. But neither Prajakta nor serial I could continue watching
Radha prem rangi rangali - watched some episodes intermittently for lead pair but found as perhaps the most unpredictable storyline ever of marathi serialworld. So stopped watching completely
Tuzya wachun karmena - Started on good note but channel wind it up tostart swapnil joshi karodo ati program.
Star Pravah - Tithalya bahutek serials khup loud asatat. Pan kahi serails tya tula kahi tack sathi follow kelya
Man oodhan varyache - for neha gadre's acting as gauri
Lek mazi ladki - meera donating kidney for Sanka's mother and the whole realisation track was very emotional and was well written by Aruna Joglekar (Reshimgathi fame). But otherwise that saket meera and then rishikesh meera parts were and are just horrible
Duheri - Watched some parts after Suvarna shyam took over as herione and old one was changed (that urmila nimbalkae was a big flop). But stopped again watched for her double role. It was also very good
Goth - The promo and title track of serial was very captivating. Watched after vilas radha marriage till they fall for each other. Then it was and is just dragging
Kulaswamini - Again it was very loud and un believable storyline. But watched for lead couple scenes (Rajas arohi)
Zee marathi
Reshimgathi - most discussed serial of this forum. Watched till Vichitra entry. Then they just tried to encash the popularity of lead pair
Eka lagnachi dusari gosht - Most focused serial of marathi serial world. But stopped watching it after umesh kamat entry. Also Ghana's indecisiveness was boring
Eka lagnachi tisari goshta - had stopped watching when isha turned as 'mi sangen tasech om ne vaagve mode. But still it was bearable due to acting of all actors
Kahe diya pardes - stopped watching aftet first few episode s since the hate for other community was the premise of story. Also could not conect with lead pair talking in Marathi and hindi throughout (Tyacha peksha mag hindi pavitra rishta changali hoti ki)
Nakatichya lagnala - Started watching for prajakta. But could bear the story for only 5 - 6 episodes. Then it was repetitive with an illogical ending
Honar sun mi hya gharchi - could not stand that know-it-all Janhavi. But that 'kanta and choti aai (prasad oak and leena bhagavat)track was excellent
Dil dosti duniyadari - till first 50 episodes. Then intermittently as those aashu makad chale increased then in end
Hindi -
Mostly the lead pair has hooked me for following serials -
Pratigya - till pratigya fall for Krishna
Diya aur bari - till sandhya fall for suraj and her education restarted
Jodha akbar - till jodha fall for Akbar
Ishaqbaaz - for shivay and anuja
Qubul hai - for asa and siya (1st pair) and for siblings love
Balika Badhu - for Anandi and Collector Saab (Shiv) love story till pratyusha was anadi and for Jagya's family disowning him and supporting Anandi
Dil mil gaye, geet, madhubala, kahi to hoga, reporter, etc again for lead pairs
Oops ... Such long list. But a nostalgic ride through memory Lane
