Could anyone tell whether this sentence is idiomatically and grammatically correct
It's very important for me to see a happy ending in movies otherwise I wouldn't be able to sleep well.
Thanks
You need a comma: It's very important for me to see a happy ending in movies, otherwise I wouldn't be able to sleep well. The tenses are a bit scrambled; "wouldn't be able to" would be better as "can't". And "to see a happy ending in movies" would be more natural as maybe "that movies have happy endings", but a native speaker might well say it the way you have it..
