Urusei Yatsura

It's kinda hard, to be honest, to watch this show after watching "Ranma ½". Clearly they have a lot in common, but Ranma does just about everything a bit better. So why do I think that this show isn't worthy of a higher score? Well...

-- Story & Writing
The overall story is simple, but I have not real issues with it. It serves as a good starting point for building the rest of the show up and there is nothing inherently bad with a simple premise. I do find the episodes lacking though and often they feel disconnected to the main story. Also, there doesn't seem ... to be much progression in the main story and while I can understand that this has advantages when writing individual chapters or episodes I quickly grow bored as the story never seems to move forward.

-- Characters & Acting
Characters vary a lot. There are some interesting characters that are fun and engaging, but most characters--including the main characters--are unfortunately lacking quite a bit. Especially the MC is a one-dimensional person with few likable traits. Many times it seems like the characters are blank canvases to simply put a story into, but since the stories are generally not too great it kinda falls flat.

-- Animation & Style
This is an early anime with a lot of inspiration from the drawing style of the time. It adds a charm to the show and while it's certainly not a masterpiece in any way I can't really fault it. The animation is okay and I've seen much worse, but it's clearly not a high quality product.

-- Music & Sound
Gotta say that "Lum's Love Song" is an absolute banger. Apart from that the music and sound is servicable and not really something you would consider either great or bad.

-- Conclusion
I can recommend this to people who want to watch a piece of history, enjoy some wacky hijinx with unlikely situations or like to see the protagonist get consistently electrocuted for oogling girls, but it's not really solid enough to warrant watching for everyone. As a product of its time it might score higher, but I'd say it's an average anime over all and while watching some of it can give a good frame of reference for similar shows I just can't bring myself to score it higher than "average".
