A terrible, bland and wasted opportunity.
This comic personified everything bad about the Next Generation (endless debating, lack of adventure, the rather slow, safe atmosphere of the show itself) and . The Next Generation is the worst of the shows to crossover with Doctor Who, the comic even shows us this with the all-too brief flashback to the 4th Doctor and the Original Enterprise crew meeting and fighting 1970s-era Cybermen. Any comic where I can say 'Kirk fights a Cyberman with Kirk doing all the Kirk fighting moves like two-handed punches and flying kicks' should be brilliant. But unfortunately, what we get is a slow and predictable story, lacking in drama, adventure and wit. More time is spent with the Doctor and the Enterprise crew sitting down all very nice and calmly talking about why they should believe the Doctor is what he claims to be instead of dealing with the plot itself.
Doctor Who is an adventure show, it's about mysteries and monsters and wonders and alien planets and adventure. The Original Trek was very much in the same vain while The Next Generation is much more trying to be deep and intelligent drama and forgetting that Roddenberry himself pitched Star Trek as a Western in Space. Picard and Company don't fit in with the mad, insane world of the Doctor and the Doctor, Amy and Rory don't fit in the safe and sterile world of the 24th Century Federation. The Borg and the Cybermen are thrown together in an alliance because... their methodology and ideology is kinda similar? IDW probably don't have the rights to use the Daleks and the Daleks in the Trek Universe probably would have presented much more of a threat than the Cybermen/Borg alliance did here. Or even have given us a new enemy with which to tax our heroes with...
The first crossover of these two great series should have been an event, an adventure across space and time and beyond the final frontier, instead, what we get is a slow and almost unreadable mess.
