Long series

I had a thought about really good series, but that are really long. Series like Bob's burgers, Smallville, supernatural, Stargate & spin-offs rest of Dr. Who, etc. If it would help series that wouldn't normally get picked because of length the amount could be shortened by doing the highest rated episodes per season,  or lowest ( might be funny to see),good lore episodes only, or 1st, middle, & last, or something like that. Just a thought that popped in my head when I realized some shows might be too long for them to consider watching, but still good.
