A mildly enjoyable way to pass the time, but still the most disappointing Telltale series to date.
However, I was slightly disappointed with the whole affair. Wallace and Gromit has its good moments and you can feel that a lot of effort and love went into making the series, but overall it still feels flat and somewhat messy.
The stories are light and silly, as you would expect from Wallace and Gromit, but they're not half as clever and refreshing as the ones I seem to remember from the actual W&G short films.
The characters are equally silly, but somehow they all feel somewhat... generic.
The puzzles are of varying quality. Most of the time they make a lot of sense and integrate well with the world and the storyline. The puzzles are enjoyable to figure out and not too difficult to solve. But on some occasions (the beginning of episode 4 comes to mind) they feel like a mess, as if the team didn't have the time to polish the game sufficiently to make it all feel like a consistent whole.
The graphics are simple but appropriate, meaning you'll be able to run W&G perfectly even on slightly older systems and it'll still feel right.
The voices and music are good, but there are a few important technical problems in this department. One is the balance between the music volume and the volume of the voices. Then there's the fact that weird things happen when multiple characters talk at the same time. And most importantly, the voices in the game are so compressed that you'll feel them grating your ears off if you happen to be using headphones. I don't understand why Telltale couldn't just use another compression algorithm or simply compress the voices less. In the age of broadband Internet, a few extra megabytes won't make a difference. Note that this is a problem with all Telltale games so far, not just W&G.
To sum things up, Wallace and Gromit is an enjoyable way to pass the time, but that's pretty much all it is. If you're new to Telltale, I'd recommend you turn to Sam and Max instead, or possibly even the new Monkey Island episodes which so far seem to be even better. If you're a veteran who just needs W&G to complete his Telltale collection, well, go ahead. Just know that even though these are decent games, they're also nothing stellar.
