What does shounen have to do with this? The beginning is a crucial part of any story. That said, since I finish everything I start anyway, a few enticing eps to get me interested aren’t necessary, so I’d rather it have a good ending instead.
@Brohamut 85 I think you're confusing most shonen anime with anime that start slow... Steins;Gate is one of the highest rated anime of all time and technically only has one season. Just because you can't get past the first episode doesn't mean the anime is will all be boring or even have more than one season.
I'm not saying you should change your ways, I'm just saying your assumptions may be wrong.
