Translation of "tedious" into Romanian

Doesn't that become tedious and worn out, like the smurf thing?

Nu devine plictisitor şi demodat, ca treaba cu ştrumpfii?

And they'll soon forget the tedious sermonizing of a few dry old men.

Vor uita repede predicile obositoare ale câtorva bătrâni ofiliţi.

I mean he's a kid and it was tedious.

Vreau să spun că el e un puşti şi că a fost plicticos.
